<p>给你一个整数数组&nbsp;<code>nums</code>&nbsp;,数组中的元素都是&nbsp;<strong></strong>&nbsp;整数。定义一个加密函数&nbsp;<code>encrypt</code>&nbsp;<code>encrypt(x)</code>&nbsp;将一个整数 <code>x</code>&nbsp;<strong>每一个</strong>&nbsp;数位都用 <code>x</code>&nbsp;中的&nbsp;<strong>最大</strong>&nbsp;数位替换。比方说&nbsp;<code>encrypt(523) = 555</code>&nbsp;<code>encrypt(213) = 333</code>&nbsp;</p>
<p>请你返回数组中所有元素加密后的 <strong></strong>&nbsp;</p>
<p>&nbsp;</p>
<p><strong class="example">示例 1</strong></p>
<div class="example-block" style="border-color: var(--border-tertiary); border-left-width: 2px; color: var(--text-secondary); font-size: .875rem; margin-bottom: 1rem; margin-top: 1rem; overflow: visible; padding-left: 1rem;">
<p><strong>输入:</strong><span class="example-io" style="font-family: Menlo,sans-serif; font-size: 0.85rem;">nums = [1,2,3]</span></p>
<p><strong>输出:</strong><span class="example-io" style="font-family: Menlo,sans-serif; font-size: 0.85rem;">6</span></p>
<p><b>解释:</b>加密后的元素位&nbsp;<code>[1,2,3]</code>&nbsp;。加密元素的和为&nbsp;<code>1 + 2 + 3 == 6</code>&nbsp;</p>
</div>
<p><strong class="example">示例 2</strong></p>
<div class="example-block" style="border-color: var(--border-tertiary); border-left-width: 2px; color: var(--text-secondary); font-size: .875rem; margin-bottom: 1rem; margin-top: 1rem; overflow: visible; padding-left: 1rem;">
<p><strong>输入:</strong><span class="example-io" style="font-family: Menlo,sans-serif; font-size: 0.85rem;">nums = [10,21,31]</span></p>
<p><strong>输出:</strong><span class="example-io" style="font-family: Menlo,sans-serif; font-size: 0.85rem;">66</span></p>
<p><b>解释:</b>加密后的元素为&nbsp;<code>[11,22,33]</code>&nbsp;。加密元素的和为&nbsp;<code>11 + 22 + 33 == 66</code></p>
</div>
<p>&nbsp;</p>
<p><strong>提示:</strong></p>
<ul>
<li><code>1 &lt;= nums.length &lt;= 50</code></li>
<li><code>1 &lt;= nums[i] &lt;= 1000</code></li>
</ul>
