<p>给你三个 <strong></strong>&nbsp;整数&nbsp;<code>num1</code>&nbsp;<code>num2</code>&nbsp;&nbsp;<code>num3</code>&nbsp;</p>
<p>数字 <code>num1</code>&nbsp;<code>num2</code>&nbsp;<code>num3</code>&nbsp;的数字答案 <code>key</code>&nbsp;是一个四位数,定义如下:</p>
<ul>
<li>一开始,如果有数字 <strong>少于</strong>&nbsp;四位数,给它补 <strong>前导 0 </strong></li>
<li>答案 <code>key</code>&nbsp;的第&nbsp;<code>i</code>&nbsp;个数位(<code>1 &lt;= i &lt;= 4</code>)为&nbsp;<code>num1</code>&nbsp;<code>num2</code>&nbsp;&nbsp;<code>num3</code>&nbsp;&nbsp;<code>i</code>&nbsp;个数位中的&nbsp;<strong>最小</strong>&nbsp;值。</li>
</ul>
<p>请你返回三个数字 <strong>没有</strong>&nbsp;前导 0 的数字答案。</p>
<p>&nbsp;</p>
<p><strong class="example">示例 1</strong></p>
<div class="example-block">
<p><span class="example-io"><b>输入:</b>num1 = 1, num2 = 10, num3 = 1000</span></p>
<p><span class="example-io"><b>输出:</b>0</span></p>
<p><b>解释:</b></p>
<p>补前导 0 后,<code>num1</code>&nbsp;变为&nbsp;<code>"0001"</code>&nbsp;<code>num2</code> 变为&nbsp;<code>"0010"</code>&nbsp;<code>num3</code>&nbsp;保持不变,为&nbsp;<code>"1000"</code>&nbsp;</p>
<ul>
<li>数字答案 <code>key</code>&nbsp;的第&nbsp;<code>1</code>&nbsp;个数位为&nbsp;<code>min(0, 0, 1)</code>&nbsp;</li>
<li>数字答案 <code>key</code>&nbsp;的第&nbsp;<code>2</code>&nbsp;个数位为&nbsp;<code>min(0, 0, 0)</code>&nbsp;</li>
<li>数字答案 <code>key</code>&nbsp;的第 <code>3</code> 个数位为&nbsp;<code>min(0, 1, 0)</code>&nbsp;</li>
<li>数字答案 <code>key</code>&nbsp;的第 <code>4</code> 个数位为&nbsp;<code>min(1, 0, 0)</code>&nbsp;</li>
</ul>
<p>所以数字答案为&nbsp;<code>"0000"</code>&nbsp;,也就是 0 。</p>
</div>
<p><strong class="example">示例 2</strong></p>
<div class="example-block">
<p><strong>输入:</strong> <span class="example-io">num1 = 987, num2 = 879, num3 = 798</span></p>
<p><span class="example-io"><b>输出:</b>777</span></p>
</div>
<p><strong class="example">示例 3</strong></p>
<div class="example-block">
<p><span class="example-io"><b>输入:</b>num1 = 1, num2 = 2, num3 = 3</span></p>
<p><span class="example-io"><b>输出:</b>1</span></p>
</div>
<p>&nbsp;</p>
<p><strong>提示:</strong></p>
<ul>
<li><code>1 &lt;= num1, num2, num3 &lt;= 9999</code></li>
</ul>
