<p>如果一个由&nbsp;<code>&#39;0&#39;</code><code>&#39;1&#39;</code>&nbsp;组成的字符串,是以一些 <code>&#39;0&#39;</code>(可能没有 <code>&#39;0&#39;</code>)后面跟着一些 <code>&#39;1&#39;</code>(也可能没有 <code>&#39;1&#39;</code>)的形式组成的,那么该字符串是&nbsp;<strong>单调递增&nbsp;</strong>的。</p>
<p>我们给出一个由字符 <code>&#39;0&#39;</code><code>&#39;1&#39;</code>&nbsp;组成的字符串 <font color="#c7254e" face="Menlo, Monaco, Consolas, Courier New, monospace"><span style="caret-color: rgb(199, 37, 78); font-size: 12.600000381469727px; background-color: rgb(249, 242, 244);">s</span></font>,我们可以将任何&nbsp;<code>&#39;0&#39;</code> 翻转为&nbsp;<code>&#39;1&#39;</code>&nbsp;或者将&nbsp;<code>&#39;1&#39;</code>&nbsp;翻转为&nbsp;<code>&#39;0&#39;</code></p>
<p>返回使 <font color="#c7254e" face="Menlo, Monaco, Consolas, Courier New, monospace"><span style="caret-color: rgb(199, 37, 78); font-size: 12.600000381469727px; background-color: rgb(249, 242, 244);">s</span></font>&nbsp;<strong>单调递增&nbsp;</strong>的最小翻转次数。</p>
<p>&nbsp;</p>
<p><strong>示例 1</strong></p>
<pre>
<strong>输入:</strong>s =<strong> </strong>&quot;00110&quot;
<strong>输出:</strong>1
<strong>解释:</strong>我们翻转最后一位得到 00111.
</pre>
<p><strong>示例 2</strong></p>
<pre>
<strong>输入:</strong>s =<strong> </strong>&quot;010110&quot;
<strong>输出:</strong>2
<strong>解释:</strong>我们翻转得到 011111或者是 000111。
</pre>
<p><strong>示例 3</strong></p>
<pre>
<strong>输入:</strong>s =<strong> </strong>&quot;00011000&quot;
<strong>输出:</strong>2
<strong>解释:</strong>我们翻转得到 00000000。
</pre>
<p>&nbsp;</p>
<p><strong>提示:</strong></p>
<ul>
<li><code>1 &lt;= s.length &lt;= 20000</code></li>
<li><font color="#c7254e" face="Menlo, Monaco, Consolas, Courier New, monospace"><span style="caret-color: rgb(199, 37, 78); font-size: 12.600000381469727px; background-color: rgb(249, 242, 244);">s</span></font> 中只包含字符&nbsp;<code>&#39;0&#39;</code>&nbsp;&nbsp;<code>&#39;1&#39;</code></li>
</ul>
