<p>You are given a string <code>text</code>. You can swap two of the characters in the <code>text</code>.</p>
 | 
						|
 | 
						|
<p>Return <em>the length of the longest substring with repeated characters</em>.</p>
 | 
						|
 | 
						|
<p> </p>
 | 
						|
<p><strong class="example">Example 1:</strong></p>
 | 
						|
 | 
						|
<pre>
 | 
						|
<strong>Input:</strong> text = "ababa"
 | 
						|
<strong>Output:</strong> 3
 | 
						|
<strong>Explanation:</strong> We can swap the first 'b' with the last 'a', or the last 'b' with the first 'a'. Then, the longest repeated character substring is "aaa" with length 3.
 | 
						|
</pre>
 | 
						|
 | 
						|
<p><strong class="example">Example 2:</strong></p>
 | 
						|
 | 
						|
<pre>
 | 
						|
<strong>Input:</strong> text = "aaabaaa"
 | 
						|
<strong>Output:</strong> 6
 | 
						|
<strong>Explanation:</strong> Swap 'b' with the last 'a' (or the first 'a'), and we get longest repeated character substring "aaaaaa" with length 6.
 | 
						|
</pre>
 | 
						|
 | 
						|
<p><strong class="example">Example 3:</strong></p>
 | 
						|
 | 
						|
<pre>
 | 
						|
<strong>Input:</strong> text = "aaaaa"
 | 
						|
<strong>Output:</strong> 5
 | 
						|
<strong>Explanation:</strong> No need to swap, longest repeated character substring is "aaaaa" with length is 5.
 |

<ul>
 | 
						|
