Find the Width of Columns of a Grid
You are given a 0-indexed m x n integer matrix 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.
Example 1
Input: grid = [[1],[22],[333]]
Output: [3]
Explanation: In the 0th column, 333 is of length 3.
Example 2
Input: grid = [[-15,1,3],[15,7,12],[5,6,-2]]
Output: [3,1,2]
Explanation: In the 0th column, only -15 is of length 3. In the 1st column, all integers are of length 1. In the 2nd column, both 12 and -2 are of length 2.
Constraints
- m == grid.length
- n == grid[i].length
- 1 <= m, n <= 100
- -10^9 <= grid[r][c] <= 10^9
