Given an array of integers, find two disjoint, contiguous subarrays such that the absolute difference between the sum of the items in each subarray is as big as possible. For each window of size k, which is a valid subarray, all possible windows of any size are also valid subsequences. More formally, given the array a, your task is to count the number of indices 0 i a. So, first we start adding element till we add k element and store result. If the current element is greater than the given value X, increment the counter otherwise add counter (counter1)2 to the number of subarrays and reinitialize counter to 0. So time complexity is O ((n-k1)k) which can also be written as O (nk) when k is.
