Function Multiply & MultiplyR
Objetive
Write two java functions, Multiply and MultiplyR, to calculate the product of two numbers using sums. T he first version must be iterative, and the second one must be recursive.
Example Code
public class Main
{
public static int MultiplyR(int n1, int n2)
{
if (n2 == 0)
{
return 0;
}
else
{
return n1 + MultiplyR(n1, n2 - 1);
}
}
public static int main(String[] args)
{
if (args.length != 2)
{
System.out.println("Enter two numbers!!");
return 1;
}
else
{
int n1 = Integer.parseInt(args[0]);
int n2 = Integer.parseInt(args[1]);
System.out.println(MultiplyR(n1, n2));
return 0;
}
}
}
