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.
Constraints:
1 <= s.length <= 500
s consists of only lowercase English letters.
思路一：遍历字符串，记录最大值
public int maxPower(String s) {
char[] chars = s.toCharArray();
char c = chars[0];
int count = 1;
int max = 1;
for (int i = 1; i < chars.length; i++) {
if (c == chars[i]) {
count++;
} else {
max = Math.max(max, count);
c = chars[i];
count = 1;
}
}
return Math.max(count, max);
}
