Problem Statement

AtCoder Inc. sells glasses and mugs.

Takahashi has a glass with a capacity of G milliliters and a mug with a capacity of M milliliters.
Here, G<M.

Initially, both the glass and the mug are empty.
After performing the following operation K times, determine how many milliliters of water are in the glass and the mug, respectively.

• When the glass is filled with water, that is, the glass contains exactly G milliliters of water, discard all the water from the glass.
• Otherwise, if the mug is empty, fill the mug with water.
• Otherwise, transfer water from the mug to the glass until the mug is empty or the glass is filled with water.

Constraints

• 1\leq K\leq 100
• 1\leq G<M\leq 1000
• G, M, and K are integers.

Sample Input 1

5 300 500

Sample Output 1

200 500

The operation will be performed as follows. Initially, both the glass and the mug are empty.

• Fill the mug with water. The glass has 0 milliliters, and the mug has 500 milliliters of water.
• Transfer water from the mug to the glass until the glass is filled. The glass has 300 milliliters, and the mug has 200 milliliters of water.
• Discard all the water from the glass. The glass has 0 milliliters, and the mug has 200 milliliters of water.
• Transfer water from the mug to the glass until the mug is empty. The glass has 200 milliliters, and the mug has 0 milliliters of water.
• Fill the mug with water. The glass has 200 milliliters, and the mug has 500 milliliters of water.

Thus, after five operations, the glass has 200 milliliters, and the mug has 500 milliliters of water. Hence, print 200 and 500 in this order, separated by a space.

Problem Statement

Given an integer X between -10^{18} and 10^{18} (inclusive), print \left\lfloor \dfrac{X}{10} \right\rfloor.

Notes

For a real number x, \left\lfloor x \right\rfloor denotes "the maximum integer not exceeding x". For example, we have \left\lfloor 4.7 \right\rfloor = 4, \left\lfloor -2.4 \right\rfloor = -3, and \left\lfloor 5 \right\rfloor = 5. (For more details, please refer to the description in the Sample Input and Output.)

Constraints

• -10^{18} \leq X \leq 10^{18}
• All values in input are integers.

Sample Input 1

47

Sample Output 1

4

The integers that do not exceed \frac{47}{10} = 4.7 are all the negative integers, 0, 1, 2, 3, and 4. The maximum integer among them is 4, so we have \left\lfloor \frac{47}{10} \right\rfloor = 4.

Sample Input 2

-24

Sample Output 2

-3

Since the maximum integer not exceeding \frac{-24}{10} = -2.4 is -3, we have \left\lfloor \frac{-24}{10} \right\rfloor = -3.
Note that -2 does not satisfy the condition, as -2 exceeds -2.4.

Sample Input 3

50

Sample Output 3

5

The maximum integer that does not exceed \frac{50}{10} = 5 is 5 itself. Thus, we have \left\lfloor \frac{50}{10} \right\rfloor = 5.

Sample Input 4

-30

Sample Output 4

-3

Just like the previous example, \left\lfloor \frac{-30}{10} \right\rfloor = -3.

Sample Input 5

987654321987654321

Sample Output 5

98765432198765432

The answer is 98765432198765432. Make sure that all the digits match.

Problem Statement

You are given a string S of length N consisting of lowercase English letters.

Find the number of non-empty substrings of S that are repetitions of one character. Here, two substrings that are equal as strings are not distinguished even if they are obtained differently.

A non-empty substring of S is a string of length at least one obtained by deleting zero or more characters from the beginning and zero or more characters from the end of S. For example, ab and abc are non-empty substrings of abc, while ac and the empty string are not.

Constraints

• 1 \leq N \leq 2\times 10^5
• S is a string of length N consisting of lowercase English letters.

Sample Input 1

6
aaabaa

Sample Output 1

4

The non-empty substrings of S that are repetitions of one character are a, aa, aaa, and b; there are four of them. Note that there are multiple ways to obtain a or aa from S, but each should only be counted once.

Problem Statement

You are given simple undirected graphs G and H, each with N vertices: vertices 1, 2, \ldots, N. Graph G has M_G edges, and its i-th edge (1\leq i\leq M_G) connects vertices u_i and v_i. Graph H has M_H edges, and its i-th edge (1\leq i\leq M_H) connects vertices a_i and b_i.

You can perform the following operation on graph H any number of times, possibly zero.

• Choose a pair of integers (i,j) satisfying 1\leq i<j\leq N. Pay A_{i,j} yen, and if there is no edge between vertices i and j in H, add one; if there is, remove it.

Find the minimum total cost required to make G and H isomorphic.

Constraints

• 1\leq N\leq8
• 0\leq M _ G\leq\dfrac{N(N-1)}2
• 0\leq M _ H\leq\dfrac{N(N-1)}2
• 1\leq u _ i\lt v _ i\leq N\ (1\leq i\leq M _ G)
• (u _ i,v _ i)\neq(u _ j,v _ j)\ (1\leq i\lt j\leq M _ G)
• 1\leq a _ i\lt b _ i\leq N\ (1\leq i\leq M _ H)
• (a _ i,b _ i)\neq(a _ j,b _ j)\ (1\leq i\lt j\leq M _ H)
• 1\leq A _ {i,j}\leq 10 ^ 6\ (1\leq i\lt j\leq N)
• All input values are integers.

The given graphs are as follows:

For example, you can perform the following four operations on H to make it isomorphic to G at a cost of 9 yen.

• Choose (i,j)=(1,3). There is an edge between vertices 1 and 3 in H, so pay 1 yen to remove it.
• Choose (i,j)=(2,5). There is no edge between vertices 2 and 5 in H, so pay 2 yen to add it.
• Choose (i,j)=(1,5). There is an edge between vertices 1 and 5 in H, so pay 1 yen to remove it.
• Choose (i,j)=(3,5). There is no edge between vertices 3 and 5 in H, so pay 5 yen to add it.

After these operations, H becomes:

You cannot make G and H isomorphic at a cost less than 9 yen, so print 9.
