Write a recursive voided function name printSquares that takes an integer parameter and print to the screen the sequence from 0 to that number and their squares. Make sure you add pre and post conditions to your method.

Solution

import java.util.Scanner;

public class SquareFunction {
   static int count = 0;
   public static void main(String args[]){
       Scanner sc = new Scanner(System.in);
       System.out.print(\"Enter any number\");
       int no = sc.nextInt();
       printSquare(no);
   }
  
   static void printSquare(int no){
       if(no<0){
           System.out.println(\"exiting no is negative\");
       }
       else{
           while(count<=no){
               System.out.println(\"Square of \"+count+\" is \"+(count*count));
               count++;
           }
       }
   }
}
