Question

Write an algorithm to find the product of two numbers

Answer 1

• ➡️➡️One simple way is to add x , y times OR add y, x times which is simple enough and is linear.⬅️⬅️

• ➡️➡️Second way is to pick any number(say x) and see which all bits are set in that number and if ith bit is set just do this: product +=y<<i//product is 0 initially and do this for all i.⬅️⬅️

hope it's help you ✔️✔️

Answer 2

Answer:

Written in Java:

import java.util.Scanner;

class HelloWorld {

   public static void main(String[] args) {

       // Creates a reader instance which takes

       // input from standard input - keyboard

       Scanner reader = new Scanner(System.in);

       System.out.print("Enter a number: ");

       int number = reader.nextInt();

       System.out.println("Enter another number: ");

       int number2 = reader.nextInt();

       int result = number*number2;

       System.out.println(result);

   }

}
