又快到期末了，LakerV想起他上个学期被考试周支配的恐惧。拼搏五日，我要上大二。成为了他的座右铭。

在考试周里，周一到周五分别要考一科课程。所以LakerV会在当天早上预习这门课程，准备下午的考试。但作为一名算法竞赛选手，LakerV相信自己不需要预习数据结构和算法这门课程。所以他在那天早上可以待在宿舍打游戏。

现在告诉你周一到周五的考试安排，以及周几，请你告诉他那天早上他在干啥。

周一到周五的考试安排：

周一：Higher mathematics

周二：Linear algebra

周三：Principle of computer composition

周四：Database system concept

周五：Data structures and algorithms （数据结构和算法）

一个正整数，表示周几

如果LakerV在预习课程，输出You were studying x! (x表示课程名称)

否则输出You were playing games!

示例1

1

You were studying Higher mathematics!

示例2

5

You were playing games!

题解：

#include
int main()
{
    int n;
    scanf("%d",&n);
    if(n==1)
        printf("You were studying Higher mathematics!n");
    else if(n==2)
        printf("You were studying Linear algebra!n");
    else if(n==3)
        printf("You were studying Principle of computer composition!n");
    else if(n==4)
        printf("You were studying Database system concept!n");
    else if(n==5)
        printf("You were playing games!n");
    return 0;        
}
