inline int decrease (int v) {
int decreasedVal = 0;
int counter = 0;
loop( v) and { decreasedVal = counter; counter++};
return decreasedValue;
}
Need to think a better way for subtracting one variable from other also
inline int subtract(int a, int b) {
loop (b) decrease(a);
}
division ??? how to compare two variables?????
return a;
