+<p>给你两个单词&nbsp;<code>word1</code> 和&nbsp;<code>word2</code>， <em>请返回将&nbsp;<code>word1</code>&nbsp;转换成&nbsp;<code>word2</code> 所使用的最少操作数</em> &nbsp;。</p>
+
+<p>你可以对一个单词进行如下三种操作：</p>
+
+<ul>
+	<li>插入一个字符</li>
+	<li>删除一个字符</li>
+	<li>替换一个字符</li>
+</ul>
+
+<p>&nbsp;</p>
+
+<p><strong>示例&nbsp;1：</strong></p>
+
+<pre>
+<strong>输入：</strong>word1 = "horse", word2 = "ros"
+<strong>输出：</strong>3
+<strong>解释：</strong>
+horse -&gt; rorse (将 'h' 替换为 'r')
+rorse -&gt; rose (删除 'r')
+rose -&gt; ros (删除 'e')
+</pre>
+
+<p><strong>示例&nbsp;2：</strong></p>
+
+<pre>
+<strong>输入：</strong>word1 = "intention", word2 = "execution"
+<strong>输出：</strong>5
+<strong>解释：</strong>
+intention -&gt; inention (删除 't')
+inention -&gt; enention (将 'i' 替换为 'e')
+enention -&gt; exention (将 'n' 替换为 'x')
+exention -&gt; exection (将 'n' 替换为 'c')
+exection -&gt; execution (插入 'u')
+</pre>
+
+<p>&nbsp;</p>
+
+<p><strong>提示：</strong></p>
+
+<ul>
+	<li><code>0 &lt;= word1.length, word2.length &lt;= 500</code></li>
+	<li><code>word1</code> 和 <code>word2</code> 由小写英文字母组成</li>
+</ul>
