<p>给定一个字符串 <code>s</code> ,请你找出其中不含有重复字符的&nbsp;<strong>最长连续子字符串&nbsp;</strong>的长度。</p>
<p>&nbsp;</p>
<p><strong>示例 1</strong></p>
<pre>
<strong>输入: </strong>s = &quot;abcabcbb&quot;
<strong>输出: </strong>3
<strong>解释:</strong> 因为无重复字符的最长子字符串是 <code>&quot;abc&quot;,所以其</code>长度为 3。
</pre>
<p><strong>示例 2</strong></p>
<pre>
<strong>输入: </strong>s = &quot;bbbbb&quot;
<strong>输出: </strong>1
<strong>解释: </strong>因为无重复字符的最长子字符串是 <code>&quot;b&quot;</code>,所以其长度为 1。
</pre>
<p><strong>示例 3</strong></p>
<pre>
<strong>输入: </strong>s = &quot;pwwkew&quot;
<strong>输出: </strong>3
<strong>解释: </strong>因为无重复字符的最长子串是&nbsp;<code>&quot;wke&quot;</code>,所以其长度为 3。
&nbsp; 请注意,你的答案必须是 <strong>子串 </strong>的长度,<code>&quot;pwke&quot;</code>&nbsp;是一个<em>子序列,</em>不是子串。
</pre>
<p><strong>示例 4</strong></p>
<pre>
<strong>输入: </strong>s = &quot;&quot;
<strong>输出: </strong>0
</pre>
<p>&nbsp;</p>
<p><strong>提示:</strong></p>
<ul>
<li><code>0 &lt;= s.length &lt;= 5 * 10<sup>4</sup></code></li>
<li><code>s</code>&nbsp;由英文字母、数字、符号和空格组成</li>
</ul>
