#include<stdio.h>
int main()
{
int x=0,y=-3;
printf("\n Enter the number :\t");
scanf("%d",&x);
int xor, and, temp,tempvar=x;
x = (x>0) ? x:(-x);
while(x>0)
{
and = x & y;
xor = x ^ y;
while(and != 0 )
{
and <<= 1;
temp = xor ^ and;
and &= xor;
xor = temp;
}
x = xor;
}
if(x==0)
printf("%d is divisible by 3",tempvar);
else
printf(" %d is not divisible by 3",tempvar);
return 0;
}
