You are given a standard 12-hour clock with analog display, an hour hand and a minute hand. How many times does the minute hand pass the hour hand in a given time interval?

Sample Input

12 50  1  2 3  8  3 20 2 45 11  011  0  3 20 1  2 12 50 3 20  3  8

Sample Output

Program 3 by team XInitial time  Final time  Passes       12:50       01:02       0       03:08       03:20       1       02:45       11:00       8       11:00       03:20       4       01:02       12:50      11       03:20       03:08      10End of program 3 by team X

 

题目的下边还有一大段，当时出在HUST上，根本分不清哪输出格式是哪个，谁知道最前边最后边那句话也需要。当时有一次试了一下加上这两句，其他地方哪里又出错了。看了题解，直接把最后一次提交的错误代码， 加上这两句输出，直接A了，坑

判断分针和时针相遇的次数

代码如下：

1 # include 
     
       2 # include
      
        3 # include
       
         4 using namespace std; 5  6 int main() 7 { 8     int a,b,c,d,ans; 9     double tmp1,tmp2,tmp3,tmp4;10     printf("Program 3 by team X\n");11     printf("Initial time  Final time  Passes\n");12     while(scanf("%d%d%d%d",&a,&b,&c,&d)!= EOF)13     {14         printf("       ");15         printf("%02d:%02d",a,b);16         printf("       ");17         printf("%02d:%02d",c,d);18         printf("      ");19         if(a==12)20             a=0;21         if(c==12)22             c=0;23         tmp2 = b/60.0;24         tmp1 = a/12.0 + tmp2/12.0;25         tmp4 = d/60.0;26         tmp3 = c/12.0 + tmp4/12.0;27                if(a==c)28         {29             if(d>=b)30             {31                 if(tmp1-tmp2>0 && tmp4-tmp3>0)32                 {33                     ans = 1;34                 }35                 else36                     ans = 0;37             }38             else39             {40                 ans = 10;41                 if(tmp1 - tmp2 > 0 )42                     ans++;43                 if(tmp4-tmp3>0)44                     ans ++;45             }46         }47         else if(a
