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.


def angleClock(hour: int, minutes: int) -> float:
    minute_angle = 6 * minutes
    hour_angle = 30 * hour + 0.5 * minutes
    angle = abs(hour_angle - minute_angle)
    return min(angle, 360 - angle)
