Make Sum Divisible by P | LeetCode 1590 | Best Intuition + Optimal Solution
Question Link: https://leetcode.com/problems/make-su...
Dive deep into the complete intuition behind LeetCode Problem 1590: Make Sum Divisible by P.
This problem requires removing the smallest possible subarray such that the remaining array sum becomes divisible by P.
In this video, we break down the prefix modulo technique, how to track remainders using a hash map, and how to identify the smallest valid subarray in O(n) time. This is one of the cleanest optimal approaches that competitive programmers use in contests.
