+
+## 题目
+
+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.
+
+**Example 3**:
+
+    Input: s = "triplepillooooow"
+    Output: 5
+
+**Example 4**:
+
+    Input: s = "hooraaaaaaaaaaay"
+    Output: 11
+
+**Example 5**:
+
+    Input: s = "tourist"
+    Output: 1
+
+**Constraints:**
+
+- 1 <= s.length <= 500
+- s consists of only lowercase English letters.
+
+## 题目大意
+
+给你一个字符串 s ，字符串的「能量」定义为：只包含一种字符的最长非空子字符串的长度。
+
+请你返回字符串的能量。
+
+## 解题思路
+
+- 顺序遍历进行统计
+
+## 代码
+
+```go
+package leetcode
+
+func maxPower(s string) int {
+	cur := s[0]
+	cnt := 1
+	ans := 1
+	for i := 1; i < len(s); i++ {
+		if cur == s[i] {
+			cnt++
+		} else {
+			if cnt > ans {
+				ans = cnt
+			}
+			cur = s[i]
+			cnt = 1
+		}
+	}
+	if cnt > ans {
+		ans = cnt
+	}
+	return ans
+}
+```
