Write code in the preferred language and attach output with it.
You know that an array has n integers between 1 and m, and the absolute difference between two adjacent values is at most 1.
Given a description of the array where some values may be unknown, your task is to count the number of arrays that match the description.
Input The first input line has two integers n and m: the array size and the upper bound for each value.
The next line has n integers x1,x2,…,xn: the contents of the array. Value 0 denotes an unknown value.
Output Print one integer: the number of arrays modulo 10^9+7.
Example:
Input: 3 5 2 0 2 Output: 3
Explanation: The arrays [2,1,2], [2,2,2] and [2,3,2] match the description.
