leetcode 1185. 一周中的第几天(C++)

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:daymonth 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"}

 

示例 1:

输入:day = 31, month = 8, year = 2019
输出:"Saturday"

示例 2:

输入:day = 18, month = 7, year = 1999
输出:"Sunday"

示例 3:

输入:day = 15, month = 8, year = 1993
输出:"Sunday"

 

提示:

  • 给出的日期一定是在 1971 到 2100 年之间的有效日期。

C++

class Solution {
public:
    string dayOfTheWeek(int day, int month, int year) 
    {
        int count=0;
        for(int i=1971;i tmp={"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
        int res=(count+5)%7;
        return tmp[res];
    }
};
