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`
- `text` consist of lowercase English characters only.
