Swap For Longest Repeated Character Substring
You are given a string text.
You are given a string text. You can swap two of the characters in the text.
Return the length of the longest substring with repeated characters.
Example 1
Input: text = "ababa"
Output: 3
Explanation: 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.
Example 2
Input: text = "aaabaaa"
Output: 6
Explanation: Swap 'b' with the last 'a' (or the first 'a'), and we get longest repeated character substring "aaaaaa" with length 6.
Example 3
Input: text = "aaaaa"
Output: 5
Explanation: No need to swap, longest repeated character substring is "aaaaa" with length is 5.
Constraints
- 1 <= text.length <= 2 * 10^4
- text consist of lowercase English characters only.
