A palindromic number is a number that remains the same when its digits are reversed.
Write a program to check palindrome.Example:-
55, 66, 77, 88, 99 are Palindrome numbers
23, 45, 90 not palindrome numbers
source Code
package com.dsacode.Probelms;
public class Palindrome {
private int reverse(int number){
int res = 0;
while(number > 0){
res = res * 10 + number %10;
number = number /10;
}
return res;
}
public boolean isPalindrome(int num){
if(num == reverse(num))
return true;
return false;
}
public static void main(String[] args) {
Palindrome p = new Palindrome();
System.out.println("Check 11 is polindrome:"+ p.isPalindrome(11));
System.out.println("Check 100 is polindrome:"+p.isPalindrome(100));
}
}
Output
Check 11 is polindrome:true Check 100 is polindrome:false
Algorithm Explanation
 | Read the number and send to reverse the number. |
| Compare reverse return with original number |
| If both are same, palindrome number |
