Find two Composite Numbers such that there difference is N
  • Last Updated : 18 Mar, 2021

Given a number N, the task is to find two composite numbers X and Y, such that difference between them is equal to N. Note that there can be multiple answers for this task. Print any one of them.
Examples: 
 

Input: N = 4
Output: X = 36, Y = 32

Input: N = 1
Output: X = 9, Y = 8

 

Approach
 

  • We have to find X – Y = N
     
  • We know, minimum value of N can be 0 or 1. If it is 0, then we can print any composite number twice. 
     
  • If N = 0, then we can print 9*N and 8 * N, because these composite numbers have minimum difference between each other, i.e., 1
     
  • We can also print 15 * N and 16 * N, but we have to print any two composite numbers, so any of these are possible. 
     

Below is the implementation of the 
 

C++




#include <bits/stdc++.h>
using namespace std;
// C++ code to Find two Composite Numbers
// such that there difference is N
 
// Function to find the two composite numbers
void find_composite_nos(int n)
{
    cout << 9 * n << " " << 8 * n;
}
 
// Driver code
int main()
{
    int n = 4;
 
    find_composite_nos(n);
 
    return 0;
}

Java




// Java code to Find two Composite Numbers
// such that there difference is N
class GFG
{
 
    // Function to find the two composite numbers
    static void find_composite_nos(int n)
    {
        System.out.println(9 * n + " " + 8 * n);
    }
     
    // Driver code
    public static void main (String[] args)
    {
        int n = 4;
     
        find_composite_nos(n);
    }
}

Python3




# Python3 code to Find two Composite Numbers
# such that their difference is N
 
# Function to find the two composite numbers
def find_composite_nos(n) :
 
    print(9 * n, 8 * n);
 
# Driver code
if __name__ == "__main__" :
 
    n = 4;
 
    find_composite_nos(n);

C#




// C# code to Find two Composite Numbers
// such that there difference is N
using System;
 
class GFG
{
 
    // Function to find the two composite numbers
    static void find_composite_nos(int n)
    {
        Console.WriteLine(9 * n + " " + 8 * n);
    }
     
    // Driver code
    public static void Main()
    {
        int n = 4;
     
        find_composite_nos(n);
    }
}

Javascript




<script>
 
// javascript code to Find two Composite Numbers
// such that there difference is N
 
// Function to find the two composite numbers
function find_composite_nos(n)
{
    document.write(9 * n + " " + 8 * n);
}
 
// Driver code
 
var n = 4;
 
find_composite_nos(n);

</script>
Output: 
36 32
