<ul>
<li>The printer can only print a sequence of <strong>the same character</strong> each time.</li>
<li>At each turn, the printer can print new characters starting from and ending at any place and will cover the original existing characters.</li>
</ul>
<p>Given a string <code>s</code>, return <em>the minimum number of turns the printer needed to print it</em>.</p>

<pre>
<strong>Input:</strong> s = &quot;aaabbb&quot;

<strong>Explanation:</strong> Print &quot;aaa&quot; first and then print &quot;bbb&quot;.
</pre>
<p><strong>Example 2:</strong></p>
<pre>
<strong>Input:</strong> s = &quot;aba&quot;
<strong>Output:</strong> 2
