When I input two negative numbers in my program that finds the LCM and HCF of a number, the HCF returns 0. It works fine for positive numbers. Here is the code for HCF module. What can I do to fix it?
static int hcf(int x, int y){
int hcf = 0;
for (int i = x; i>=1; i--){
if (y%i==0 && x%i==0){
hcf = i;
break;
}
}
return hcf;
}
If x is less or equal to 0, i will be initialized with x value and the for loop won't execute anything due to the condition i >= 1, thus the method will return 0.
Probably you should try to initialize i to (int)Math.abs(x).
