LeetCode ProblemFind the Width of Columns of a Grid
You are given a 0-indexed m x n integer matrix grid. The width of a column is the maximum length of its integers. Return an integer array ans of size n where ans[i] is the width of the ith column. The length of an integer x with len digits is equal to len if x is non-negative, and len + 1 otherwise.
