You are given a string <code>s</code>. We want to partition the string into as many parts as possible so that each letter appears in at most one part. For example, the string <code>&quot;ababcc&quot;</code> can be partitioned into <code>[&quot;abab&quot;, &quot;cc&quot;]</code>, but partitions such as <code>[&quot;aba&quot;, &quot;bcc&quot;]</code> or <code>[&quot;ab&quot;, &quot;ab&quot;, &quot;cc&quot;]</code> are invalid.

Note that the partition is done so that after concatenating all the parts in order, the resultant string should be <code>s</code>.

Return a list of integers representing the size of these parts.

&nbsp;
Example 1:

<pre>
Input: s = &quot;ababcbacadefegdehijhklij&quot;
Output: [9,7,8]
Explanation:
The partition is &quot;ababcbaca&quot;, &quot;defegde&quot;, &quot;hijhklij&quot;.
This is a partition so that each letter appears in at most one part.
A partition like &quot;ababcbacadefegde&quot;, &quot;hijhklij&quot; is incorrect, because it splits s into less parts.
</pre>

Example 2:

<pre>
Input: s = &quot;eccbbbbdec&quot;
Output: [10]
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= s.length &lt;= 500</code></li>
	<li><code>s</code> consists of lowercase English letters.</li>
</ul>

给你一个字符串 <code>s</code> 。我们要把这个字符串划分为尽可能多的片段，同一字母最多出现在一个片段中。例如，字符串&nbsp;<code>"ababcc"</code> 能够被分为 <code>["abab", "cc"]</code>，但类似&nbsp;<code>["aba", "bcc"]</code> 或&nbsp;<code>["ab", "ab", "cc"]</code> 的划分是非法的。

注意，划分结果需要满足：将所有划分结果按顺序连接，得到的字符串仍然是 <code>s</code> 。

返回一个表示每个字符串片段的长度的列表。

&nbsp;
示例 1：

<pre>
输入：s = "ababcbacadefegdehijhklij"
输出：[9,7,8]
解释：
划分结果为 "ababcbaca"、"defegde"、"hijhklij" 。
每个字母最多出现在一个片段中。
像 "ababcbacadefegde", "hijhklij" 这样的划分是错误的，因为划分的片段数较少。 </pre>

示例 2：

<pre>
输入：s = "eccbbbbdec"
输出：[10]
</pre>

&nbsp;

提示：

<ul>
	<li><code>1 &lt;= s.length &lt;= 500</code></li>
	<li><code>s</code> 仅由小写英文字母组成</li>
</ul>
