Write a java program to print following pattern when n=5:

1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
 

import java.util.Scanner;

public class NumberPattern {

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

System.out.println("Enter Size: ");

int n=sc.nextInt();

for (int i = 1; i <=2*n-1; i++) {

int k=1;

if(i<=n) {

for(int j=1;j<=i;j++)  {

System.out.print(k+" ");

k++;

}

} 

else {

for(int j=1;j<2*n-i+1;j++) {

System.out.print(k+" ");

k++;

}

}

System.out.println();

}

}

}
