Hi, I have tried the possible 780 test cases and checked it with UVA toolkit.
My test cases were from:

00:00 > 12:59 (780 in total)

Unfortunately all the cases has matched with UVA toolkit but I am yet to get "Accepted" ....

here's my code....help me out soon


===========================================================================================================================
#include <stdio.h>

int main()
{
//freopen("out.txt","r",stdin);

int h,m;
int t,i;

double hours,mins,total;
int hrs,mns;
scanf ("%d",&i);


for (t=0;t<i;t++)
{
scanf ("%d:%d",&h,&m);

if (h==12)
h=0;

hours=h*60;



total=hours+m;

total=720-total;
hours=total/60;

//printf ("%lf ",hours);

hours=(int)hours;
//printf ("%lf ",hours);

mins=(total/60)-hours;
mins=mins*60;
//printf ("%lf ",mins);

hrs=hours;
mns=mins;

if (hrs==0)
printf ("12:");

else if (hrs<10)
printf ("0%d:",hrs);
else
printf ("%d:",hrs);

if (mns<10)
