【leetcode】1344. Angle Between Hands of a Clock

标签：its   src   correct   cep   out   assets   inpu   actual   div   

题目如下：

Given two numbers, hour and minutes. Return the smaller angle (in sexagesimal units) formed between the hour and the minute hand.

Example 1:

Input: hour = 12, minutes = 30
Output: 165

Example 2:

Input: hour = 3, minutes = 30
Output: 75

Example 3:

Input: hour = 3, minutes = 15
Output: 7.5

Example 4:

Input: hour = 4, minutes = 50
Output: 155

Example 5:

Input: hour = 12, minutes = 0
Output: 0

Constraints:

• 1 <= hour <= 12
• 0 <= minutes <= 59
• Answers within 10^-5 of the actual value will be accepted as correct.

解题思路：很有意思的题目，关键就是要判断时针的位置，时针偏离的角度和当前的分钟有关。

代码如下：

class Solution(object):
    def angleClock(self, hour, minutes):
        """
        :type hour: int
        :type minutes: int
        :rtype: float
        """
        if hour == 12:
            hour = 0
        hour = hour * 5
        hour += float(minutes) / float(60) * 5
        res =  abs(minutes - hour)/float(60) * 360
        if res > 180:
            res = 360 - res
        return res
