Consecutive Characters

The power of the string is the maximum length of a non-empty substring that contains only one unique character.

Given a string s, return the power of s.

Example 1:

Input: s = "leetcode"
Output: 2
Explanation: The substring "ee" is of length 2 with the character 'e' only.

Example 2:

Input: s = "abbcccddddeeeeedcba"
Output: 5
Explanation: The substring "eeeee" is of length 5 with the character 'e' only.

Solution

class Solution:
    def maxPower(self, s: str) -> int:
        c = 1
        out = 1
        for i in range(1, len(s)):
            if s[i] == s[i-1]:
                c += 1
                out = max(c, out)
            else:
                c = 1
        return out
