Sum Of Palindrome Elements Of An Array

Sum Of Palindrome Elements Of An Array


Write a program to display the sum of palindrome elements in a n x n matrix.

import java.io.*; class SumOfPalindromes { public static void main(String ar[])throws Exception { BufferedReader ob=new BufferedReader( new InputStreamReader(System.in)); int i,j,n,t,r,sum=0; int a[][]=new int[3][3]; System.out.println("Enter "+(3*3)+" elements "); for(i=0;i< 3;i++) { for(j=0;j< 3;j++) { a[i][j]=Integer.parseInt(ob.readLine()); } } for(i=0;i< 3;i++) { for(j=0;j< 3;j++) { n=a[i][j]; r=0; while(n>0) { t=n%10; r=r*10+t; n=n/10; } if(r==a[i][j]) sum=sum+a[i][j]; } } System.out.println("\nSum of palindrome elements = "+ sum); } }
