- 3. Longest Substring Without Rep
Find the length of the longest substringTof a given string (consists of lowercase letters only) such that every character inTappears no less thanktimes.
Example 1: Input: = "aaabb", k = 3 Output: 3
The longest substring is "aaa", as 'a' is repeated 3 times.
Example 2: Input: s = "ababbc", k = 2 Output: 5
The longest substring is "ababb", as 'a' is repeated 2 times and 'b' is repeated 3 times.
devide and conquer 虽然也是使用递归， 但是是二分式递归， 速度要快很多. 将字符串出现次数放到26个字符数组中， 查找个数小于k的， 分别算左边和右边的最大值，
