The task is to minimize the sum of these chosen . Finally, return count. Now we will use Kadanes Algorithm to find the maximum subarray sum and minimum subarray sum. Given an array arr[] containing N elements, the task is to count the number of sub-arrays whose XOR of all the elements is equal to the sum of all the elements in the subarray. Max sum of M non-overlapping subarrays of size K. 3. Naive Approach: The naive approach for this problem is to consider all the sub-arrays and for every subarray, check if the XOR is equal to the sum. Input: arr [] = {1, 2, 3, 1, 5} Output: 11. .
