题目 #

Given a date, return the corresponding day of the week for that date.

The input is given as three integers representing the daymonth and year respectively.

Return the answer as one of the following values {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}.

Example 1:

Input: day = 31, month = 8, year = 2019
Output: "Saturday"

Example 2:

Input: day = 18, month = 7, year = 1999
Output: "Sunday"

Example 3:

Input: day = 15, month = 8, year = 1993
Output: "Sunday"

Constraints:

  • The given dates are valid dates between the years 1971 and 2100.

题目大意 #

给你一个日期,请你设计一个算法来判断它是对应一周中的哪一天。输入为三个整数:day、month 和 year,分别表示日、月、年。

您返回的结果必须是这几个值中的一个 {“Sunday”, “Monday”, “Tuesday”, “Wednesday”, “Thursday”, “Friday”, “Saturday”}。

提示:

  • 给出的日期一定是在 1971 到 2100 年之间的有效日期。

解题思路 #

  • 给出一个日期,要求算出这一天是星期几。
  • 简单题,按照常识计算即可。

代码 #


package leetcode

import "time"

func dayOfTheWeek(day int, month int, year int) string {
	return time.Date(year, time.Month(month), day, 0, 0, 0, 0, time.Local).Weekday().String()
}
