<p>给你一个由若干 0 和 1 组成的字符串 <code>s</code> ,请你计算并返回将该字符串分割成两个 <strong>非空</strong> 子字符串(即&nbsp;<strong></strong> 子字符串和 <strong></strong> 子字符串)所能获得的最大得分。</p>
<p>「分割字符串的得分」为 <strong></strong> 子字符串中 <strong>0</strong> 的数量加上 <strong></strong> 子字符串中 <strong>1</strong> 的数量。</p>
<p>&nbsp;</p>
<p><strong>示例 1</strong></p>
<pre><strong>输入:</strong>s = &quot;011101&quot;
<strong>输出:</strong>5
<strong>解释:</strong>
将字符串 s 划分为两个非空子字符串的可行方案有:
左子字符串 = &quot;0&quot; 且 右子字符串 = &quot;11101&quot;,得分 = 1 + 4 = 5
左子字符串 = &quot;01&quot; 且 右子字符串 = &quot;1101&quot;,得分 = 1 + 3 = 4
左子字符串 = &quot;011&quot; 且 右子字符串 = &quot;101&quot;,得分 = 1 + 2 = 3
左子字符串 = &quot;0111&quot; 且 右子字符串 = &quot;01&quot;,得分 = 1 + 1 = 2
左子字符串 = &quot;01110&quot; 且 右子字符串 = &quot;1&quot;,得分 = 2 + 1 = 3
</pre>
<p><strong>示例 2</strong></p>
<pre><strong>输入:</strong>s = &quot;00111&quot;
<strong>输出:</strong>5
<strong>解释:</strong>当 左子字符串 = &quot;00&quot; 且 右子字符串 = &quot;111&quot; 时,我们得到最大得分 = 2 + 3 = 5
</pre>
<p><strong>示例 3</strong></p>
<pre><strong>输入:</strong>s = &quot;1111&quot;
<strong>输出:</strong>3
</pre>
<p>&nbsp;</p>
<p><strong>提示:</strong></p>
<ul>
<li><code>2 &lt;= s.length &lt;= 500</code></li>
<li>字符串 <code>s</code> 仅由字符 <code>&#39;0&#39;</code><code>&#39;1&#39;</code> 组成。</li>
</ul>
