Vasya wants to divide this array into two non-empty consecutive parts (the prefix and the suffix) so that the sum of all elements in the first part equals to the sum of elements in the second part. First of all, if you can divide an array such that the maximum sum is at most x x x, you can also divide the array such that the maximum sum is at most y > x y > x y > x with Vitaly has an array of n distinct integers. Then you can divide the array into some number x of subarrays such that every subarray has sum < max_sum. Reload to refresh your session.
