What's wrong with the following results?

And - if nothings's wrong, why do I get WA?

I've tried int, long and double as co-ordinate types (in C).

My Accepted code outputs same answer as you.

I read all coordinates as double type number, and sum all distances as double type.
After calculate total distance, convert to long type number.
Then,

Code: Select all

    long total;
    double hour, minute;
...
...
...
    total = (long)(calc_distances());   /* convert to long */
    total *= 2;
    hour = (double)(total / 20000);
    total -= 20000 * hour;
    minute = (double)total / (double)20000 * 60;

    if((int)ceil(minute)==60) {
      minute = 0;
      hour += 1;
    }
    printf("%d:", (int)hour);
    if(minute<10) printf("0");
    printf("%d\n", (int)ceil(minute));

There might be a lot of uselessness in this code.

Best regards.

Hmmmm... seems like changing hypot() to sqrt() gets you AC.

I know that these are pretty bad thoughts and offtopic in any case... but what was meant by

official solution from Waterloo

? Does something valuable can be found on web?

Please i need a help...
I am sure that i got the right distance but does this output is right

Code: Select all

long double sec = (2*dist*60)/20000.0;
		sec = ceil(sec);
		

		long long minutes = sec  / 60;		
		long long seconds = sec  - minutes*60;

		
		cout<<minutes<<":";
		if(seconds<9)
			cout<<"0";
		cout<<seconds;
		if(cases != 0)
			cout<<"\n\n";

I am sure the problem in converting total seconds to nearest minute
