1156 - Swap For Longest Repeated Character Substring.
Medium
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 * 104
