Snuke can change a string t of length N into a string t' of length N - 1 under the following rule:
* For each i (1 ≤ i ≤ N - 1), the i-th character of t' must be either the i-th or (i + 1)-th character of t.
There is a string s consisting of lowercase English letters. Snuke's objective is to apply the above operation to s repeatedly so that all the characters in s are the same. Find the minimum necessary number of operations.

Snuke has many tetrominos. The number of I-, O-, T-, J-, L-, S- and Z-tetrominos in his possession are a_I, a_O, a_T, a_J, a_L, a_S and a_Z, respectively. Snuke will join K of his tetrominos to form a rectangle that is two squares tall and 2K squares wide. Here, the following rules must be followed:
* When placing each tetromino, rotation is allowed, but reflection is not.
* Each square in the rectangle must be covered by exactly one tetromino.
* No part of each tetromino may be outside the rectangle.
Snuke wants to form as large a rectangle as possible. Find the maximum possible value of K.

Snuke has many tetrominos. The number of I-, O-, T-, J-, L-, S- and Z-tetrominos in his possession are a_I, a_O, a_T, a_J, a_L, a_S and a_Z, respectively. Snuke will join K of his tetrominos to form a rectangle that is two squares tall and 2K squares wide. Here, the following rules must be followed:
* When placing each tetromino, rotation is allowed, but reflection is not.
* Each square in the rectangle must be covered by exactly one tetromino.
* No part of each tetromino may be outside the rectangle.
Snuke wants to form as large a rectangle as possible. Find the maximum possible value of K.

There is a sequence of length 2N: A_1, A_2, ..., A_{2N}. Each A_i is either -1 or an integer between 1 and 2N (inclusive). Any integer other than -1 appears at most once in {A_i}.
For each i such that A_i = -1, Snuke replaces A_i with an integer between 1 and 2N (inclusive), so that {A_i} will be a permutation of 1, 2, ..., 2N. Then, he finds a sequence of length N, B_1, B_2, ..., B_N, as B_i = min(A_{2i-1}, A_{2i}).
Find the number of different sequences that B_1, B_2, ..., B_N can be, modulo 10^9 + 7.
Constraints
* 1 \leq N \leq 300

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
There is a sequence of length 2N: A_1, A_2, ..., A_{2N}. Each A_i is either -1 or an integer between 1 and 2N (inclusive). Any integer other than -1 appears at most once in {A_i}.
For each i such that A_i = -1, Snuke replaces A_i with an integer between 1 and 2N (inclusive), so that {A_i} will be a permutation of 1, 2, ..., 2N. Then, he finds a sequence of length N, B_1, B_2, ..., B_N, as B_i = min(A_{2i-1}, A_{2i}).
Find the number of different sequences that B_1, B_2, ..., B_N can be, modulo 10^9 + 7.
Constraints
* 1 \leq N \leq 300
* A_i = -1 or 1 \leq A_i \leq 2N.
* If A_i \neq -1, A_j \neq -1, then A_i \neq A_j. (i \neq j)

There are N non-negative integers written on the blackboard: A_1, ..., A_N.
Snuke can perform the following two operations at most K times in total in any order:
* Operation A: Replace each integer X on the blackboard with X divided by 2, rounded down to the nearest integer.
* Operation B: Replace each integer X on the blackboard with X minus 1. This operation cannot be performed if one or more 0s are written on the blackboard.
Find the number of the different possible combinations of integers written on the blackboard after Snuke performs the operations, modulo 1,000,000,007.
Constraints
* 1 \leq N \leq 200
* 1 \leq A_i \leq 10^{18}
* 1 \leq K \leq 10^{18}

Snuke and Raccoon have a heap of N cards. The i-th card from the top has the integer a_i written on it.
They will share these cards. First, Snuke will take some number of cards from the top of the heap, then Raccoon will take all the remaining cards. Here, both Snuke and Raccoon have to take at least one card.
Let the sum of the integers on Snuke's cards and Raccoon's cards be x and y, respectively. They would like to minimize |x-y|. Find the minimum possible value of |x-y|.
