Given an integer N as the input and a start integer S, print the pattern as given in the Example Input/Output section.

Input Format:
The first line contains S and N, each separated by a space.

Output Format:
2N lines containing the desired pattern.

Boundary Conditions:
2 <= N <= 50
1 <= S <= 20

Example Input/Output 1:
Input:
3 4

Output:
3
4 4
5 5 5
6 6 6 6

Code:

Java:

import java.util.Scanner;

public class Hello {

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        int start = sc.nextInt();

        int N = sc.nextInt();

        printPattern(start, N);

         

    }

static void printPattern(int base, int N){

int i,j,x=0,flag=0;

for(i=0;i<=N*2+1;i++)

{

   if(i<=N)

        x=i;

    else   

        x--;

    for(j=0;j<x;j++)

    {

     System.out.print(base-1+" ");  

    }

    if(i<N)

    base++;

    else

    {

    if(flag==0)

       { i--;flag=1;}

    else

        base--;

    }

   

    System.out.println();

}

}
