Minimum Element After Replacement With Digit Sum
<p>You are given an integer array <code>nums</code>.</p>

<p>You replace each element in <code>nums</code> with the <strong>sum</strong> of its digits.</p>

<p>Return the <strong>minimum</strong> element in <code>nums</code> after all replacements.</p>

<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>

<div class="example-block">
<p><strong>Input:</strong> <span class="example-io">nums = [10,12,13,14]</span></p>

<p><strong>Output:</strong> <span class="example-io">1</span></p>

<p><strong>Explanation:</strong></p>

<p><code>nums</code> becomes <code>[1, 3, 4, 5]</code> after all replacements, with minimum element 1.</p>
</div>

<div class="example-block">
<p><strong>Input:</strong> <span class="example-io">nums = [1,2,3,4]</span></p>

<p><strong>Output:</strong> <span class="example-io">1</span></p>

<p><strong>Explanation:</strong></p>

<p><code>nums</code> becomes <code>[1, 2, 3, 4]</code> after all replacements, with minimum element 1.</p>
</div>

<div class="example-block">
<p><strong>Input:</strong> <span class="example-io">nums = [999,19,199]</span></p>

<p><strong>Output:</strong> <span class="example-io">10</span></p>

<p><strong>Explanation:</strong></p>

<p><code>nums</code> becomes <code>[27, 10, 19]</code> after all replacements, with minimum element 10.</p>
