2639 - Find the Width of Columns of a Grid.

Easy

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 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
  • -109 <= grid[r][c] <= 109
