[Solved] 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.

Question

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.

Constraints:

• 1 <= s.length <= 500
• s consists of only lowercase English letters.

Python Solution

class Solution:
    def maxPower(self, s: str) -> int:
        i=0
        m=1
        ma=1

        for i in range(len(s)-1):
            if s[i]==s[i+1]:
                m+=1
            else:
                ma = max(ma,m)
                m=1

        return(max(ma,m))
