Hello I am Sourav. I almost finished the problem but judge showing me 100% wrong answer where the program is almost correct.

#include <stdio.h>

int main()
{
    int h, m, hp, mp;
    while(scanf("%d%d", &h, &m)!=EOF)
    {
        if(h==0 && m==0)
        {
            hp = 0; mp = 0;
        }
        else if(h==360 && m==360){
            hp = 0; mp = 0;
        }
        else{
            hp = h/30; mp = m/6;
        }
        printf("%02d:%02d\n", hp, mp);
        if(h==0 && m==0)
        {
            break;
        }
    }
    return 0;
}
