题意是:有两个时钟,分别慢了k秒和m秒,12:00开始一起走,就下次重合的时间是多少,首先先求出它们的差值,在让43200除以它就得到多岁天后重合,然后就好算了。

看AC代码:

 1 #include <bits/stdc++.h>
 2 using namespace std;
 3 #define ll long long
 4 const int R = 12*60*60;
 5 const int D = 24*60*60;
 6 
 7 int main(){
 8     int k,m;
 9     while(cin>>k>>m){
10         int cnt = abs(k-m);
11         if(cnt == 0){
12             printf("%d %d 12:00\n",k,m);
13             continue;
14         }
15         double d = R*1.0/cnt;
16         int t = (int)(d*(D-k)/60+0.5)%D;
17         int h = t/60;
18         h%=12;
19         if(h==0) h = 12;
20         int mm = t%60;
21         printf("%d %d %02d:%02d\n",k,m,h,mm);
22     }
23     return 0;
24 }
