String
Binary Search
You are given a binary string s of length n and an integer numOps.
You are allowed to perform the following operation on s at most numOps times:
You need to minimize the length of the longest substring of s such that all the characters in the substring are identical.
Return the minimum length after the operations.
Examples
Example 1
Input: s = "000001", numOps = 1
Output: 2
Explanation:
By changing s[2] to '1' , s becomes "001001" . The longest substrings with identical characters are s[0..1] and s[3..4] .
Example 2
Input: s = "0000", numOps = 2
Output: 1
Explanation:
By changing s[0] and s[2] to '1' , s becomes "1010" .
Example 3
Input: s = "0101", numOps = 0
Output: 1
Constraints
1 <= n == s.length <= 105
s consists only of '0' and '1'.
0 <= numOps <= n
