【题目大意】给定一个时间点,求时针和分针夹角,时针和秒针夹角,分针和秒针夹角

模拟题,注意细节

代码:

#include<bits/stdc++.h>using namespace std;inline int read(){    int c=0,f=1;    char ch=getchar();    while(ch<'0'||ch>'9'){if(ch=='-')f=-1;ch=getchar();}    while(ch>='0'&&ch<='9'){c=c*10+ch-'0';ch=getchar();}    return c*f;}int gcd(int a,int b){return b==0?a:gcd(b,a%b);}int main(){  int t,h,m,s;   t=read();   while(t--){       scanf("%d:%d:%d",&h,&m,&s);       h%=12;       m%=60;       s%=60;       int ss=s*720;    //秒针走过的角度       int mm=720*m+12*s;  //分针走过的角度       int hh=3600*h+60*m+s;  //时针走过的角度      //计算角度之差       int hm=abs(hh-mm);       int hs=abs(hh-ss);       int ms=abs(mm-ss);      //判断       hm=min(hm,120*360-hm);       hs=min(hs,120*360-hs);       ms=min(ms,120*360-ms);      //取最大公约数       int ghm=gcd(hm,120);       int ghs=gcd(hs,120);       int gms=gcd(ms,120);       if(ghm==120) cout<<hm/120;       else cout<<hm/ghm<<"/"<<120/ghm;       if(ghs==120) cout<<" "<<hs/120<<" ";       else cout<<" "<<hs/ghs<<"/"<<120/ghs<<" ";        if(gms==120) cout<<ms/120<<" "<<endl;       else cout<<ms/gms<<"/"<<120/gms<<" "<<endl;   } return 0;}
