Problem Statement

Given integers A and B, find A+B.
This is a N-choice problem; the i-th choice is C_i.
Print the index of the correct choice.

Constraints

• All values in the input are integers.
• 1 \le N \le 300
• 1 \le A,B \le 1000
• 1 \le C_i \le 2000
• C_i are pairwise distinct. In other words, no two choices have the same value.
• There is exactly one i such that A+B=C_i. In other words, there is always a unique correct choice.

Sample Input 1

200 300 400

Sample Output 1

2

We have 125+175 = 300.
The first, second, and third choices are 200, 300, and 400, respectively.
Thus, the 2-nd choice is correct, so 2 should be printed.

Problem Statement

Takahashi is developing an RPG. He has decided to write a code that checks whether two maps are equal.

We have grids A and B with H horizontal rows and W vertical columns. Each cell in the grid has a symbol # or . written on it.
The symbols written on the cell at the i-th row from the top and j-th column from the left in A and B are denoted by A_{i, j} and B_{i, j}, respectively.

The following two operations are called a vertical shift and horizontal shift.

• For each j=1, 2, \dots, W, simultaneously do the following:
  • simultaneously replace A_{1,j}, A_{2,j}, \dots, A_{H-1, j}, A_{H,j} with A_{2,j}, A_{3,j}, \dots, A_{H,j}, A_{1,j}.
• For each i = 1, 2, \dots, H, simultaneously do the following:
  • simultaneously replace A_{i,1}, A_{i,2}, \dots, A_{i,W-1}, A_{i,W} with A_{i, 2}, A_{i, 3}, \dots, A_{i,W}, A_{i,1}.

Is there a pair of non-negative integers (s, t) that satisfies the following condition? Print Yes if there is, and No otherwise.

• After applying a vertical shift s times and a horizontal shift t times, A is equal to B.

Here, A is said to be equal to B if and only if A_{i, j} = B_{i, j} for all integer pairs (i, j) such that 1 \leq i \leq H and 1 \leq j \leq W.

Constraints

• 2 \leq H, W \leq 30
• A_{i,j} is # or ., and so is B_{i,j}.
• H and W are integers.

Problem Statement

We have a grid with H horizontal rows and W vertical columns. We denote by (i, j) the cell at the i-th row from the top and j-th column from the left of the grid.
Each cell in the grid has a symbol # or . written on it. Let C[i][j] be the character written on (i, j). For integers i and j such that at least one of 1 \leq i \leq H and 1 \leq j \leq W is violated, we define C[i][j] to be ..

(4n+1) squares, consisting of (a, b) and (a+d,b+d),(a+d,b-d),(a-d,b+d),(a-d,b-d) (1 \leq d \leq n, 1 \leq n), are said to be a cross of size n centered at (a,b) if and only if all of the following conditions are satisfied:

• C[a][b] is #.
• C[a+d][b+d],C[a+d][b-d],C[a-d][b+d], and C[a-d][b-d] are all #, for all integers d such that 1 \leq d \leq n,
• At least one of C[a+n+1][b+n+1],C[a+n+1][b-n-1],C[a-n-1][b+n+1], and C[a-n-1][b-n-1] is ..

For example, the grid in the following figure has a cross of size 1 centered at (2, 2) and another of size 2 centered at (3, 7).

The grid has some crosses. No # is written on the cells except for those comprising a cross.
Additionally, no two squares that comprise two different crosses share a corner. The two grids in the following figure are the examples of grids where two squares that comprise different crosses share a corner; such grids are not given as an input. For example, the left grid is invalid because (3, 3) and (4, 4) share a corner.

Let N = \min(H, W), and S_n be the number of crosses of size n. Find S_1, S_2, \dots, S_N.

Constraints

• 3 \leq H, W \leq 100
• C[i][j] is # or ..
• No two different squares that comprise two different crosses share a corner.
• H and W are integers.

• 300 = 2^2 \times 3 \times 5^2

Problem Statement

You have an integer 1 and a die that shows integers between 1 and 6 (inclusive) with equal probability.
You repeat the following operation while your integer is strictly less than N:

• Cast a die. If it shows x, multiply your integer by x.

Find the probability, modulo 998244353, that your integer ends up being N.

Constraints

• 2 \leq N \leq 10^{18}
• N is an integer.

Sample Input 1

6

Sample Output 1

239578645

One of the possible procedures is as follows.

• Initially, your integer is 1.
• You cast a die, and it shows 2. Your integer becomes 1 \times 2 = 2.
• You cast a die, and it shows 4. Your integer becomes 2 \times 4 = 8.
• Now your integer is not less than 6, so you terminate the procedure.

Your integer ends up being 8, which is not equal to N = 6.

The probability that your integer ends up being 6 is \frac{7}{25}. Since 239578645 \times 25 \equiv 7 \pmod{998244353}, print 239578645.

Sample Input 2

7

Sample Output 2

No matter what the die shows, your integer never ends up being 7.

You are given a string S of length N consisting of o and x, and integers M and K.
S is guaranteed to contain at least one x.

Let T be the string of length NM obtained by concatenating M copies of S. Consider replacing exactly K x's in T with o.
Your objective is to have as long a contiguous substring consisting of o as possible in the resulting T.
Find the maximum length of a contiguous substring consisting of o that you can obtain.

Problem Statement

We define the general term a_n of a sequence a_0, a_1, a_2, \dots by:

Given an integer N, find the sum, modulo 998244353, of a_m over all non-negative integers m such that m\text{ AND }N = m. (\text{AND} denotes the bitwise AND.)
