<p>给你一个字符串&nbsp;<code>s</code>&nbsp;,它由某个字符串&nbsp;<code>t</code>&nbsp;和若干&nbsp;<code>t</code>&nbsp;&nbsp;<strong>同位字符串</strong>&nbsp;连接而成。</p>
<p>请你返回字符串 <code>t</code>&nbsp;<strong>最小</strong>&nbsp;可能长度。</p>
<p><strong>同位字符串</strong>&nbsp;指的是重新排列一个单词得到的另外一个字符串,原来字符串中的每个字符在新字符串中都恰好只使用一次。</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>s = "abba"</span></p>
<p><span class="example-io"><b>输出:</b>2</span></p>
<p><strong>解释:</strong></p>
<p>一个可能的字符串&nbsp;<code>t</code>&nbsp;&nbsp;<code>"ba"</code>&nbsp;</p>
</div>
<p><strong class="example">示例 2</strong></p>
<div class="example-block">
<p><span class="example-io"><b>输入:</b>s = "cdef"</span></p>
<p><span class="example-io"><b>输出:</b>4</span></p>
<p><strong>解释:</strong></p>
<p>一个可能的字符串&nbsp;<code>t</code>&nbsp;&nbsp;<code>"cdef"</code>&nbsp;,注意&nbsp;<code>t</code>&nbsp;可能等于&nbsp;<code>s</code>&nbsp;</p>
</div>
<p>&nbsp;</p>
<p><strong>提示:</strong></p>
<ul>
<li><code>1 &lt;= s.length &lt;= 10<sup>5</sup></code></li>
<li><code>s</code>&nbsp;只包含小写英文字母。</li>
</ul>
