my programe can pass all your tests#,but i WA at ural's test#1,why...?

does someone can help me?

#include <stdio.h>

main()

{

int i,j,k;

scanf("%lf%lf%lf%lf",&ch[1],&ch[2],&ch[3],&ch[4]);

for(i=1;i<=4;i++)

{

time1[i]=(int)ch[i];

time2[i]=ch[i]-time1[i];

if((i==2 || i==4) && time1[i]<time1[i-1]) time1[i]+=24;

}

hour=time1[3]-time1[4]+time1[2]-time1[1];

mini=time2[3]-time2[4]+time2[2]-time2[1];

hour=abs(hour+mini*5.0/3.0);

hour/=2;

if(hour>5) hour=5;

printf("%.0lf",hour);

}

Re: Who give me some tests?

Please, explain me why the answer is 5?

Re: Who give me some tests?

answer is 5, because max difference in time = 5 hours))

then all answers >5 , =5 !

test 3 is wrong. please, read the statement.

The time of flights there and back may differ from each other not more than by 10 minutes

if answer is one, the time of the first flight is 3 hours

and the second - 2 hours 5 minutes...

of course, those times differ by 55 minutes...

Re: Who give me some tests?

There should be min(12 - h, h) instead of min(h, 5), test:

01.00 00.00

00.00 03.00

Answer 2
