Subarray Sum Equals K A simple solution is to use two nested loops.The outer loop picks a starting element, the inner loop considers all elements (on right side of current start) as ending element. Example : arr [] = {1, 4, -2, -2, 5, -4, 3} If we consider all prefix sums, we can notice that there is a subarray with 0 sum when : 1) Either a prefix sum repeats or 2) Or prefix sum becomes 0. For every substring, we will check if it is a palindrome or not, and if it is then we will take the longest among them. Odd Even Linked List 329. Space Complexity.
