【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;
