partitionString

Given a string <code>s</code>, partition the string into one or more substrings such that the characters in each substring are unique. That is, no letter appears in a single substring more than once.

Return the minimum number of substrings in such a partition.

Note that each character should belong to exactly one substring in a partition.

&nbsp;
Example 1:

<pre>
Input: s = &quot;abacaba&quot;
Output: 4
Explanation:
Two possible partitions are (&quot;a&quot;,&quot;ba&quot;,&quot;cab&quot;,&quot;a&quot;) and (&quot;ab&quot;,&quot;a&quot;,&quot;ca&quot;,&quot;ba&quot;).
It can be shown that 4 is the minimum number of substrings needed.
</pre>

Example 2:

<pre>
Input: s = &quot;ssssss&quot;
Output: 6
Explanation:
The only valid partition is (&quot;s&quot;,&quot;s&quot;,&quot;s&quot;,&quot;s&quot;,&quot;s&quot;,&quot;s&quot;).
</pre>

&nbsp;
Constraints:

<ul>
	<li><code>1 &lt;= s.length &lt;= 105</code></li>
	<li><code>s</code> consists of only English lowercase letters.</li>
</ul>
