3402. Minimum Operations to Make Columns Strictly Increasing

You are given a m x n matrix grid consisting of non-negative integers. In one operation, you can increment the value of any grid[i][j] by 1. Return the minimum number of operations needed to make all columns of grid strictly increasing. Example 1: Input: grid = [[3,2],[1,3],[3,4],[0,1]] Output: 15 Explanation: - To make the 0th column strictly increasing, we can apply 3 operations on grid
