Asked in companies
You are given an array 'ARR' of 'N' positive integers. You need to find the length of the longest switching contiguous subarray.
An array is called Switching if all the elements at even indices are equal and all the elements at odd indices are also equal.
For Example :
If the given 'ARR' is [1, 4, 1, 4, 3, 2, 3, 0]. Then {1, 4, 1, 4}, {3, 2, 3}, {3, 0}, {0} are some of the switching subarrays. But {1, 4, 3}, {1, 4, 1, 4, 3, 2, 3} are not.
