又是一道模拟题

题解就不写了

#include <cstdio>
#include <cstring>
#include <iostream>
#include <algorithm>
using namespace std;
inline int read(){
	int x=0,f=1,ch=getchar();
	while(ch<'0'||ch>'9'){if(ch=='-')f=-1;ch=getchar();}
	while(ch>='0'&&ch<='9'){x=x*10+ch-'0';ch=getchar();}
	return x*f;
}
int h,m;
int main(){
	h=read(),m=read();
	while(h!=0||m!=0){
		int a1=720/60*m;
		int a2=720/12*h+60/60*m;
		if(a1>a2){
			int temp=a1;a1=a2;a2=temp;
		}
		int ans=min(a2-a1,720-a2+a1);
		if(ans&1) printf("At %d:%02d the angle is %d.5 degrees.\n",h,m,ans>>1);
		else printf("At %d:%02d the angle is %d.0 degrees.\n",h,m,ans>>1);
		h=read(),m=read();
	}
	return 0;
}
