2639. Find the Width of Columns of a Grid Easy

1/**
2 * [2639] Find the Width of Columns of a Grid
3 *
4 * You are given a 0-indexed m x n integer matrix grid. The width of a column is the maximum length of its integers.
5 * 
6 * 	For example, if grid = [[-10], [3], [12]], the width of the only column is 3 since -10 is of length 3.
7 * 
8 * Return an integer array ans of size n where ans[i] is the width of the i^th column.
9 * The length of an integer x with len digits is equal to len if x is non-negative, and len + 1 otherwise.
10 *  
11 * <strong class="example">Example 1:
12 * 
13 * Input: grid = [[1],[22],[333]]
14 * Output: [3]
15 * Explanation: In the 0^th column, 333 is of length 3.
16 * 
17 * <strong class="example">Example 2:
18 * 
19 * Input: grid = [[-15,1,3],[15,7,12],[5,6,-2]]
20 * Output: [3,1,2]
21 * Explanation: 
22 * In the 0^th column, only -15 is of length 3.
23 * In the 1^st column, all integers are of length 1. 
24 * In the 2^nd column, both 12 and -2 are of length 2.
25 * 
26 *  
27 * Constraints:
28 * 
29 * 	m == grid.length
30 * 	n == grid[i].length
31 * 	1 <= m, n <= 100 
32 * 	-10^9 <= grid[r][c] <= 10^9
33 *
