This is my solution for the problem ALCHEMY on SPOJ :
#include <stdio.h>
int main (void)
{
float a = 1000, b = 37;
unsigned long int x, y;
float z = a / b;
for (x,y; x != -1, y != -1;)
{
scanf ("%lu %lu", &x, &y);
if ((float)x / (float)y == z && x != -1 && y != -1)
printf ("Y\n");
else if (x / y != z && x != -1 && y != -1)
printf ("N\n");
else if ( y == 0)
return 1;
else if (x == -1 && y == -1)
return 876;
}
return 0;
}
Even if I enter x and y as 1000 and 37 respectively, the first if statement is evaluated as false and it prints N instead of Y . Is it even possible to solve this problem the way I m trying and using float ? What am I doing wrong?
Please try to run it once.
