Palindromic Number Pyramid
This program prints a palindromic number pyramid.
Problem Statement
Write a Java program that prints a palindromic number pyramid with 5 rows.
Source Code
| 1 | public class PalindromicPyramid { |
| 2 | public static void main(String[] args) { |
| 3 | int n = 5; |
| 4 | for(int i=1; i<=n; i++) { |
| 5 | for(int j=i; j<n; j++) System.out.print(" "); |
| 6 | for(int j=1; j<=i; j++) System.out.print(j); |
| 7 | for(int j=i-1; j>=1; j--) System.out.print(j); |
| 8 | System.out.println(); |
| 9 | } |
| 10 | } |
| 11 | } |
Program Output
1 121 12321 1234321 123454321
Explanation
Each row prints ascending numbers from 1 to the row index followed by descending numbers back to 1, forming a palindromic sequence per row and demonstrating symmetry in numeric patterns.
