WebApr 6, 2024 · The idea is to consider every subarray and find the length of even and odd subarrays. Follow the steps below to solve the problem: Iterate for every subarray from i = 0 ; Make a nested loop, iterate from j = i + 1; Now, check if a[j – 1] is even and a[j] is odd or a[j – 1] is odd and a[j] is even then increment count
