CHALLENGE ACCEPTED.

Question:-

Write a program in Java/QBASIC to display the following pattern.

1 2 3 4 5 4 3 2 1

1 2 3 4 A 4 3 2 1

1 2 3 B C D 3 2 1

1 I J K L M N O 1

Program:-

This is written in Java.

import java.util.*;

public class Main {

public static void main(String[] args)

{

int n=5;

int a=n, b=n-1, c=0;

char ch='A';

for(int i=1;i<=n;i++)

{

for(int j=1;j<=a;j++)

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

for(int j=1;j<c;j++)

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

for(int j=b;j>=1;j--)

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

c=c+2;

a--;

if(i!=1)

b--;

System.out.println();

}

}

}

Output:-

1 2 3 4 5 4 3 2 1
