# 1156. Swap For Longest Repeated Character Substring

https://leetcode.com/problems/swap-for-longest-repeated-character-substring

## Description

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", which its length is 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", which its length is 6.
```

**Example 3:**

```
**Input:** text = "aaabbaaa"
**Output:** 4
```

**Example 4:**

```
**Input:** text = "aaaaa"
**Output:** 5
**Explanation:** No need to swap, longest repeated character substring is "aaaaa", length is 5.
```

**Example 5:**

```
**Input:** text = "abcdef"
**Output:** 1
```

**Constraints:**

* `1 <= text.length <= 2 * 104`
* `text` consist of lowercase English characters only.
