3
+ <ol>

+ <li> Let <b>a</b> be an integer that coprime to <b>m</b>, that is, <b>gcd(a, m) = 1</b>. The minimal positive integer <b>k</b> such that <b>m</b> divides <b>a<sup>k</sup> &#8722; 1</b> is called the <i>multiplicative order of <b>a</b> modulo <b>m</b></i> and denoted as <b>ord<sub>m</sub>(a)</b>. For example, <b> ord<sub>7</sub>(2) = 3</b> since <b>2<sup>3</sup> &#8722; 1 = 7</b> is divisible by <b>7</b> but <b>2<sup>1</sup> &#8722; 1</b> and <b>2<sup>2</sup> &#8722; 1</b> are not. It can be proven that <b>ord<sub>m</sub>(a)</b> exists for every <b>a</b> that coprime to <b>m</b>.
5

6
+ <li> Denote by <b>L(m)</b> the maximal possible multiplicative order of some number modulo <b>m</b>. That is, <b>L(m) = max{ord<sub>m</sub>(a) : 1 &le; a &le; m, gcd(a, m)=1}</b>. For example, <p><center><b>L(5) = max{ ord<sub>5</sub>(1), ord<sub>5</sub>(2), ord<sub>5</sub>(3), ord<sub>5</sub>(4)} = max{1, 4, 4, 2} = 4</b></center></p> and <p><center><b>L(6) = max{ord<sub>6</sub>(1), ord<sub>6</sub>(5)} = max{1, 2} = 2.</b></center></p>
7
+
8
+ <li> Denote by <b>N(m)</b> the number of positive integers <b>a &le; m</b> such that <b> ord<sub>m</sub>(a) = L(m)</b>. For example, <b>N(5) = 2</b>, <b>N(6) = 1</b>, <b>N(8) = 3</b> (numbers that have maximal multiplicative order modulo <b>8</b> are <b>3, 5</b> and <b>7</b>).
9
+ </ol>
10
+ <p>Now your task is to find for the given positive integers <b>L</b> and <b>R</b> such that <b>L &#8804; R</b> the product
11
+ <p><center><b>N(L) &#8729; N(L+1) &#8729; ... &#8729; N(R)</b></center></p>
12
+ modulo <b>10<sup>9</sup> + 7</b>.</p>
13
+
14
+ <h3>Input</h3>
15
+ <p>The first line contains a positive integer <b>T</b>, the number of test cases. <b>T</b> test cases follow. The only line of each test case contains two space separated positive integers <b>L</b> and <b>R</b>.</p>
16

17
+ <h3>Output</h3>
18
+ <p>For each of the test cases numbered in order from <b>1</b> to <b>T</b>, output "Case #i: " followed by the value of required product modulo <b>10<sup>9</sup> + 7</b>.</p>

1
+ Let's start with some notations and definitions. Let **m** be the fixed
2
+ positive integer.
3
+
4
+ 1. Let **a** be an integer that coprime to **m**, that is, **gcd(a, m) = 1**. The minimal positive integer **k** such that **m** divides **ak − 1** is called the _multiplicative order of **a** modulo **m**_ and denoted as **ordm(a)**. For example, ** ord7(2) = 3** since **23 − 1 = 7** is divisible by **7** but **21 − 1** and **22 − 1** are not. It can be proven that **ordm(a)** exists for every **a** that coprime to **m**.
5
+ 2. Denote by **L(m)** the maximal possible multiplicative order of some number modulo **m**. That is, **L(m) = max{ordm(a) : 1 ≤ a ≤ m, gcd(a, m)=1}**. For example,
6
+
7
+ **L(5) = max{ ord5(1), ord5(2), ord5(3), ord5(4)} = max{1, 4, 4, 2} = 4**
8
+
9
+ and
10
+
11
+ **L(6) = max{ord6(1), ord6(5)} = max{1, 2} = 2.**
12
+
13
+ 3. Denote by **N(m)** the number of positive integers **a ≤ m** such that ** ordm(a) = L(m)**. For example, **N(5) = 2**, **N(6) = 1**, **N(8) = 3** (numbers that have maximal multiplicative order modulo **8** are **3, 5** and **7**).
14
+
15
+ Now your task is to find for the given positive integers **L** and **R** such
16
+ that **L ≤ R** the product
17
+
18
+ **N(L) ∙ N(L+1) ∙ ... ∙ N(R)**
19
+
20
+ modulo **109 \+ 7**.
21
+
22
+ ### Input
23
+
24
+ The first line contains a positive integer **T**, the number of test cases.
25
+ **T** test cases follow. The only line of each test case contains two space
26
+ separated positive integers **L** and **R**.
27
+
28
+ ### Output
29
+
30
+ For each of the test cases numbered in order from **1** to **T**, output "Case
31
+ #i: " followed by the value of required product modulo **109 \+ 7**.
32
+
33
+ ### Constraints

36

1
+ Alfredo Spaghetti really likes soup, especially when it contains alphabet
2
+ pasta. Every day he constructs a sentence from letters, places the letters
3
+ into a bowl of broth and enjoys delicious alphabet soup.
4
+
5
+ Today, after constructing the sentence, Alfredo remembered that the Facebook
6
+ Hacker Cup starts today! Thus, he decided to construct the phrase "HACKERCUP".
7
+ As he already added the letters to the broth, he is stuck with the letters he
8
+ originally selected. Help Alfredo determine how many times he can place the
9
+ word "HACKERCUP" side-by-side using the letters in his soup.
10
+
11
+ ### Input
12
+
13
+ The first line of the input file contains a single integer T: the number of
14
+ test cases. T lines follow, each representing a single test case with a
15
+ sequence of upper-case letters and spaces: the original sentence Alfredo
16
+ constructed.
17
+
18
+ ### Output
19
+
20
+ Output T lines, one for each test case. For each case, output "Case #t: n",
21
+ where t is the test case number (starting from 1) and n is the number of times
22
+ the word "HACKERCUP" can be placed side-by-side using the letters from the
23
+ sentence.
24
+
25
+ ### Constraints
26
+
27
+ * 1 < T ≤ 20
28
+ * Sentences contain only the upper-case letters A-Z and the space character
29
+ * Each sentence contains at least one letter, and contains at most 1,000 characters, including spaces

1
+ <p>You have encountered a new fancy online auction that offers lots of products.
2
+ You are only interested in their price and weight. We shall say that
3
+ product A is strictly preferred over product B if A costs less than B and is not
4
+ heavier (they may be of equal weight) or if A weighs less and is not more
5
+ expensive (they can have equal price).
6
+ </p>
7
+
8
+ <p>We shall call a product A a bargain if there is no product B such that B is
9
+ better than A. Similarly, we shall call a product C a terrible deal if there
10
+ exists no product D such that C is better than D. Note that according to our
11
+ definitions, the same product may be both a bargain and a terrible deal! Only
12
+ wacky auctioneers sell such products though.
13
+ </p>
14
+
15
+ <p>One day you wonder how many terrible deals and bargains are offered. The
16
+ number of products, N, is too large for your human-sized brain though.
17
+ Fortunately, you discovered that the auction manager is terribly lazy and
18
+ decided to sell the products based on a very simple pseudo-random number
19
+ generator.
20
+ </p>
21
+
22
+ <p>If product i has price P<sub>i</sub> and weight W<sub>i</sub>, then the
23
+ following holds for product i+1:
24
+ <ul>
25
+ <li> P<sub>i</sub> = ((A*P<sub>i-1</sub> + B) mod M) + 1 (for all i = 2..N)
26
+ <li> W<sub>i</sub> = ((C*W<sub>i-1</sub> + D) mod K) + 1 (for all i = 2..N)
27
+ </ul>
28
+ </p>
29
+
30
+ <p>You carefully calculated the parameters for the generator (P<sub>1</sub>,
31
+ W<sub>1</sub>, M, K, A, B, C and D). Now you want to calculate the
32
+ number of terrible deals and bargains on the site.
33
+ </p>
34
+
35
+ <h3>Input</h3>
36
+ <p>The first line of the input file contains a single integer T: the number of
37
+ test cases. T lines follow, each representing a single test case with
38
+ 9 space-separated integers: N, P<sub>1</sub>, W<sub>1</sub>, M, K, A, B, C and
39
+ D.
40
+ </p>
41
+
42
+ <h3>Output</h3>
43
+ <p>Output T lines, one for each test case. For each case, output "Case #t: a b",
44
+ where t is the test case number (starting from 1), a is the number of terrible deals
45
+ and b is the number of bargains.
46

1
+ You have encountered a new fancy online auction that offers lots of products.
2
+ You are only interested in their price and weight. We shall say that product A
3
+ is strictly preferred over product B if A costs less than B and is not heavier
4
+ (they may be of equal weight) or if A weighs less and is not more expensive
5
+ (they can have equal price).
6
+
7
+ We shall call a product A a bargain if there is no product B such that B is
8
+ better than A. Similarly, we shall call a product C a terrible deal if there
9
+ exists no product D such that C is better than D. Note that according to our
10
+ definitions, the same product may be both a bargain and a terrible deal! Only
11
+ wacky auctioneers sell such products though.
12
+
13
+ One day you wonder how many terrible deals and bargains are offered. The
14
+ number of products, N, is too large for your human-sized brain though.
15
+ Fortunately, you discovered that the auction manager is terribly lazy and
16
+ decided to sell the products based on a very simple pseudo-random number
17
+ generator.
18
+
19
+ If product i has price Pi and weight Wi, then the following holds for product
20
+ i+1:
21
+
22
+ * Pi = ((A*Pi-1 \+ B) mod M) + 1 (for all i = 2..N)
23
+ * Wi = ((C*Wi-1 \+ D) mod K) + 1 (for all i = 2..N)
24
+
25
+ You carefully calculated the parameters for the generator (P1, W1, M, K, A, B,
26
+ C and D). Now you want to calculate the number of terrible deals and bargains
27
+ on the site.
28
+
29
+ ### Input
30
+
31
+ The first line of the input file contains a single integer T: the number of
32
+ test cases. T lines follow, each representing a single test case with 9 space-
33
+ separated integers: N, P1, W1, M, K, A, B, C and D.
34
+
35
+ ### Output
36
+
37
+ Output T lines, one for each test case. For each case, output "Case #t: a b",
38
+ where t is the test case number (starting from 1), a is the number of terrible
39
+ deals and b is the number of bargains.
40
+
41
+ ### Constraints
42
+
43
+ * 1 ≤ T ≤ 20
44
+ * 1 ≤ N ≤ 1018
45
+ * 1 ≤ M, K ≤ 107
46
+ * 1 ≤ P1 ≤ M
47
+ * 1 ≤ W_1 ≤ K
48
+ * 0 ≤ A,B,C,D ≤ 109

1
+ <p>We are starting preparations for Hacker Cup 2013 really early. Our first step
2
+ is to prepare billboards to advertise the contest. We have text for hundreds of
3
+ billboards, but we need your help to design them.
4
+ </p>
5
+
6
+ <p>The billboards are of different sizes, but are all rectangular. The billboard widths and heights are all integers. We will
7
+ supply you with the size in inches and the text we want printed. We want you to
8
+ tell us how large we can print the text, such that it fits on the billboard
9
+ without splitting any words across lines. Since this is to attract hackers like
10
+ yourself, we will use a monospace font, meaning that all characters are of the
11
+ same width (e.g.. 'l' and 'm' take up the same horizontal space, as do space
12
+ characters). The characters in our font are of equal width and height, and there
13
+ will be no additional spacing between adjacent characters or adjacent rows. If you print a word on one line and print the next word on the next line, you do not need to print a space between them.
14
+ </p>
15
+
16
+ <p>Let's say we want to print the text "Facebook Hacker Cup 2013" on a 350x100"
17
+ billboard. If we use a font size of 33" per character, then we can print
18
+ "Facebook" on the first line, "Hacker Cup" on the second and "2013" on the
19
+ third. The widest of the three lines is "Hacker Cup", which is 330" wide. There
20
+ are three lines, so the total height is 99". We cannot go any larger.
21
+ </p>
22
+
23
+ <h3>Input</h3>
24
+
25
+ <p>The first line of the input file contains a single integer T: the number of
26
+ test cases. T lines follow, each representing a single test case in the form "W
27
+ H S". W and H are the width and height in inches of the available space. S is
28
+ the text to be written.
29
+ </p>
30
+
31
+ <h3>Output</h3>
32
+
33
+ <p>Output T lines, one for each test case. For each case, output "Case #t: s",
34

1
+ We are starting preparations for Hacker Cup 2013 really early. Our first step
2
+ is to prepare billboards to advertise the contest. We have text for hundreds
3
+ of billboards, but we need your help to design them.
4
+
5
+ The billboards are of different sizes, but are all rectangular. The billboard
6
+ widths and heights are all integers. We will supply you with the size in
7
+ inches and the text we want printed. We want you to tell us how large we can
8
+ print the text, such that it fits on the billboard without splitting any words
9
+ across lines. Since this is to attract hackers like yourself, we will use a
10
+ monospace font, meaning that all characters are of the same width (e.g.. 'l'
11
+ and 'm' take up the same horizontal space, as do space characters). The
12
+ characters in our font are of equal width and height, and there will be no
13
+ additional spacing between adjacent characters or adjacent rows. If you print
14
+ a word on one line and print the next word on the next line, you do not need
15
+ to print a space between them.
16
+
17
+ Let's say we want to print the text "Facebook Hacker Cup 2013" on a 350x100"
18
+ billboard. If we use a font size of 33" per character, then we can print
19
+ "Facebook" on the first line, "Hacker Cup" on the second and "2013" on the
20
+ third. The widest of the three lines is "Hacker Cup", which is 330" wide.
21
+ There are three lines, so the total height is 99". We cannot go any larger.
22
+
23
+ ### Input
24
+
25
+ The first line of the input file contains a single integer T: the number of
26
+ test cases. T lines follow, each representing a single test case in the form
27
+ "W H S". W and H are the width and height in inches of the available space. S
28
+ is the text to be written.
29
+
30
+ ### Output
31
+
32
+ Output T lines, one for each test case. For each case, output "Case #t: s",
33
+ where t is the test case number (starting from 1) and s is the maximum font
34
+ size, in inches per character, we can use. The size must be an integral number
35
+ of inches. If the text does not fit when printed at a size of 1", then output
36
+ 0.
37
+
38
+ ### Constraints
39
+
40
+ * 1 ≤ T ≤ 20
41
+ * 1 ≤ W, H ≤ 1,000
42
+ * The text will contain only lower-case letters a-z, upper-case letters A-Z, digits 0-9 and the space character
43
+ * The text will not start or end with the space character, and will never contain two adjacent space characters
44
+ * The text in each case contains at most 1,000 characters

+ Merge sort is one of the classic sorting algorithms. It divides the input
2
+ array into two halves, recursively sorts each half, then merges the two sorted
3
+ halves.
4
+
5
+ In this problem merge sort is used to sort an array of integers in ascending
6
+ order. The exact behavior is given by the following pseudo-code:
7
+
8
+ function merge_sort(arr):
9
+ n = arr.length()
10
+ if n <= 1:
11
+ return arr
12
+ // arr is indexed 0 through n-1, inclusive
13
+ mid = floor(n/2)
14
+ first_half = merge_sort(arr[0..mid-1])
15
+ second_half = merge_sort(arr[mid..n-1])
16
+ return merge(first_half, second_half)
17
+ function merge(arr1, arr2):
18
+ result = []
19
+ while arr1.length() > 0 and arr2.length() > 0:
20
+ if arr1[0] < arr2[0]:
21
+ print '1' // for debugging
22
+ result.append(arr1[0])
23
+ arr1.remove_first()

37

38
+ ### Input
39
+
40
+ The first line of the input file contains an integer **T**. This is followed
41
+ by **T** test cases, each of which has two lines. The first line of each test
42
+ case contains the length of the original sequence, **N**. The second line
43

58
+ ### Constraints
59
+
60
+ 5 ≤ **T** ≤ 20
61
+ 2 ≤ N ≤ 10,000
62
+
63
+ ### Examples
64
+
65
+ In the first example, N is 2 and the debug sequence is `1`. The original
66
+ sequence was 1 2 or 2 1. The debug sequence tells us that the first number was
67
+ smaller than the second so we know the sequence was 1 2. The checksum is 994.
68
+
69
+ In the second example, N is 2 and the debug sequence is `2`. This time the
70
+ original sequence is 2 1.
71
+
72
+ In the third example, N is 4 and the debug sequence is `12212`. The original
73
+ sequence is 2 4 3 1.

+ <p>Some engineers got tired of dealing with all the different ways of encoding status messages, so they decided to invent their own. In their new scheme, an encoded status message consists of a sequence of integers representing the characters in the message, separated by spaces. Each integer is between 1 and <strong>M</strong>, inclusive. The integers do not have leading zeroes. Unfortunately they decided to compress the encoded status messages by removing all the spaces!
2
+ </p>
3
+ <p>
4
+ Your task is to figure out how many different encoded status messages a given compressed status message could have originally been. Because this number can be very large, you should return the answer modulo 4207849484 (0xfaceb00c in hex).
5
+ </p>
6
+ <p>
7
+ For example, if the compressed status message is "12" it might have originally been "1&nbsp;2", or it might have originally been "12". The compressed status messages are between 1 and 1000 characters long, inclusive. Due to database corruption, a compressed status may contain sequences of digits that could not result from removing the spaces in an encoded status message.
8
+ </p>
9
+ <h3>Input</h3>
10
+ <p>
11
+ The input begins with a single integer, <strong>N</strong>, the number of compressed status messages you must analyze. This will be followed by <strong>N</strong> compressed status messages, each consisting of an integer <strong>M</strong>, the highest character code for that database, then the compressed status message, which will be a string of digits each in the range '0' to '9', inclusive. All tokens in the input will be separated by some whitespace.
12
+ </p>
13
+ <h3>Output</h3>
14
+ <p>
15
+ For each of the test cases numbered in order from 1 to <strong>N</strong>, output "Case #<strong>i</strong>: " followed by a single integer containing the number of different encoded status messages that could be represented by the corresponding compressed sequence modulo 4207849484. If none are possible, output a 0.

1
+ Some engineers got tired of dealing with all the different ways of encoding
2
+ status messages, so they decided to invent their own. In their new scheme, an
3
+ encoded status message consists of a sequence of integers representing the
4
+ characters in the message, separated by spaces. Each integer is between 1 and
5
+ **M**, inclusive. The integers do not have leading zeroes. Unfortunately they
6
+ decided to compress the encoded status messages by removing all the spaces!
7
+
8
+ Your task is to figure out how many different encoded status messages a given
9
+ compressed status message could have originally been. Because this number can
10
+ be very large, you should return the answer modulo 4207849484 (0xfaceb00c in
11
+ hex).
12
+
13
+ For example, if the compressed status message is "12" it might have originally
14
+ been "1 2", or it might have originally been "12". The compressed status
15
+ messages are between 1 and 1000 characters long, inclusive. Due to database
16
+ corruption, a compressed status may contain sequences of digits that could not
17
+ result from removing the spaces in an encoded status message.
18
+
19
+ ### Input
20
+
21
+ The input begins with a single integer, **N**, the number of compressed status
22
+ messages you must analyze. This will be followed by **N** compressed status
23
+ messages, each consisting of an integer **M**, the highest character code for
24
+ that database, then the compressed status message, which will be a string of
25
+ digits each in the range '0' to '9', inclusive. All tokens in the input will
26
+ be separated by some whitespace.
27
+
28
+ ### Output
29
+
30
+ For each of the test cases numbered in order from 1 to **N**, output "Case
31
+ #**i**: " followed by a single integer containing the number of different
32
+ encoded status messages that could be represented by the corresponding
33
+ compressed sequence modulo 4207849484. If none are possible, output a 0.
34
+
35
+ ### Constraints
36
+
37
+ 5 ≤ **N** ≤ 25
38
+ 2 ≤ **M** ≤ 255
39
+ 1 ≤ length of encoded status ≤ 1000
