Find 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.

For example, if grid = [[-10], [3], [12]], the width of the only column is 3 since -10 is of length 3.

Return an integer array ans of size n where ans[i] is the width of the i^th 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

  1
 22
333

Inputgrid = [[1],[22],[333]]

Output[3]

In the 0^th column, 333 is of length 3.

Example 2

-15   1   3
 15   7  12
  5   6  -2

Inputgrid = [[-15,1,3],[15,7,12],[5,6,-2]]

Output[3,1,2]

In the 0^th column, only -15 is of length 3; in the 1^st column, all integers are of length 1; in the 2^nd column, both 12 and -2 are of length 2.
