Description

tab: English
 
<p>Given an input string (<code>s</code>) and a pattern (<code>p</code>), implement wildcard pattern matching with support for <code>&#39;?&#39;</code> and <code>&#39;*&#39;</code> where:</p>
 
<ul>
	<li><code>&#39;?&#39;</code> Matches any single character.</li>
	<li><code>&#39;*&#39;</code> Matches any sequence of characters (including the empty sequence).</li>
</ul>
 
<p>The matching should cover the <strong>entire</strong> input string (not partial).</p>
 
<p>&nbsp;</p>
<p><strong class="example">Example 1:</strong></p>
 
<pre>
<strong>Input:</strong> s = &quot;aa&quot;, p = &quot;a&quot;
<strong>Output:</strong> false
<strong>Explanation:</strong> &quot;a&quot; does not match the entire string &quot;aa&quot;.
</pre>
 
<p><strong class="example">Example 2:</strong></p>
 
<pre>
<strong>Input:</strong> s = &quot;aa&quot;, p = &quot;*&quot;
<strong>Output:</strong> true
<strong>Explanation:</strong>&nbsp;&#39;*&#39; matches any sequence.
</pre>
 
<p><strong class="example">Example 3:</strong></p>
 
<pre>
<strong>Input:</strong> s = &quot;cb&quot;, p = &quot;?a&quot;
<strong>Output:</strong> false
<strong>Explanation:</strong>&nbsp;&#39;?&#39; matches &#39;c&#39;, but the second letter is &#39;a&#39;, which does not match &#39;b&#39;.
</pre>
 
<p>&nbsp;</p>
<p><strong>Constraints:</strong></p>
 
<ul>
	<li><code>0 &lt;= s.length, p.length &lt;= 2000</code></li>
	<li><code>s</code> contains only lowercase English letters.</li>
	<li><code>p</code> contains only lowercase English letters, <code>&#39;?&#39;</code> or <code>&#39;*&#39;</code>.</li>
</ul>

<div class="title__3Vvk">给你一个输入字符串 (<code>s</code>) 和一个字符模式 (<code>p</code>) ，请你实现一个支持 <code>'?'</code> 和 <code>'*'</code> 匹配规则的通配符匹配：</div>
 
<ul>
	<li class="title__3Vvk"><code>'?'</code> 可以匹配任何单个字符。</li>
	<li class="title__3Vvk"><code>'*'</code> 可以匹配任意字符序列（包括空字符序列）。</li>
</ul>
 
<div class="original__bRMd">
<div>
<p>判定匹配成功的充要条件是：字符模式必须能够 <strong>完全匹配</strong> 输入字符串（而不是部分匹配）。</p>
</div>
</div>
&nbsp;
 
<p><strong class="example">示例 1：</strong></p>
 
<pre>
<strong>输入：</strong>s = "aa", p = "a"
<strong>输出：</strong>false
<strong>解释：</strong>"a" 无法匹配 "aa" 整个字符串。
</pre>
 
<p><strong class="example">示例 2：</strong></p>
 
<pre>
<strong>输入：</strong>s = "aa", p = "*"
<strong>输出：</strong>true
<strong>解释：</strong>'*' 可以匹配任意字符串。
</pre>
 
<p><strong class="example">示例 3：</strong></p>
 
<pre>
<strong>输入：</strong>s = "cb", p = "?a"
<strong>输出：</strong>false
<strong>解释：</strong>'?' 可以匹配 'c', 但第二个 'a' 无法匹配 'b'。
</pre>
 
<p>&nbsp;</p>
 
<p><strong>提示：</strong></p>
 
<ul>
	<li><code>0 &lt;= s.length, p.length &lt;= 2000</code></li>
	<li><code>s</code> 仅由小写英文字母组成</li>
	<li><code>p</code> 仅由小写英文字母、<code>'?'</code> 或 <code>'*'</code> 组成</li>
</ul>
