2639. Find the Width of Columns of a Grid

Easy

106

15

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:**

Input:grid = [[1],[22],[333]]Output:[3]Explanation:In the 0^{th}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 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.

**Constraints:**

`m == grid.length`

`n == grid[i].length`

`1 <= m, n <= 100`

`-10`

^{9}<= grid[r][c] <= 10^{9}
