2639 - Find the Width of Columns of a Grid.<p>Easy</p>
<p>You are given a <strong>0-indexed</strong> <code>m x n</code> integer matrix <code>grid</code>. The width of a column is the maximum <strong>length</strong> of its integers.</p>
<ul>
<li>For example, if <code>grid = \[\[-10], [3], [12]]</code>, the width of the only column is <code>3</code> since <code>-10</code> is of length <code>3</code>.</li>
</ul>
<p>Return <em>an integer array</em> <code>ans</code> <em>of size</em> <code>n</code> <em>where</em> <code>ans[i]</code> <em>is the width of the</em> <code>i<sup>th</sup></code> <em>column</em>.</p>
<p>The <strong>length</strong> of an integer <code>x</code> with <code>len</code> digits is equal to <code>len</code> if <code>x</code> is non-negative, and <code>len + 1</code> otherwise.</p>
<p><strong>Example 1:</strong></p>
<p><strong>Input:</strong> grid = [[1],[22],[333]]</p>
<p><strong>Output:</strong> [3]</p>
<p><strong>Explanation:</strong> In the 0<sup>th</sup> column, 333 is of length 3.</p>
<p><strong>Example 2:</strong></p>
<p><strong>Input:</strong> grid = [[-15,1,3],[15,7,12],[5,6,-2]]</p>
<p><strong>Output:</strong> [3,1,2]</p>
<p><strong>Explanation:</strong></p>
<p>In the 0<sup>th</sup> column, only -15 is of length 3.</p>
<p>In the 1<sup>st</sup> column, all integers are of length 1.</p>
<p>In the 2<sup>nd</sup> column, both 12 and -2 are of length 2.</p>
<p><strong>Constraints:</strong></p>
<ul>
<li><code>m == grid.length</code></li>
<li><code>n == grid[i].length</code></li>
<li><code>1 <= m, n <= 100</code></li>
<li><code>-10<sup>9</sup> <= grid[r][c] <= 10<sup>9</sup></code></li>
</ul>
