Palindrome Numbers

What is a Palindrome Number?

Palindrome number is a number which remains same even after reversing its digits.

CaseExamples

Palindrome Number in Java

Let’s print palindrome number list using a for loop.

package com.techstackjournal.java.basics;

public class Palindrome {

	public static void main(String[] args) {

		for (int i = 0; i < 500; i++) {

			if (isPalindrome(i)) {
				System.out.printf("%d ",i);
			}
		}
	}

	private static boolean isPalindrome(int number) {
		int reminder;
		int reverseNum = 0;
		int tempNum = number;

		while (tempNum != 0) {
			reminder = tempNum % 10;
			reverseNum = reverseNum * 10 + reminder;
			tempNum = tempNum / 10;
		}
		return number == reverseNum;
	}

}

Palindrome Number in C language

#include <stdio.h>

short isPalindrome(int number)
{
    int reminder;
    int reverseNum = 0;
    int tempNum = number;

    while (tempNum != 0)
    {
        reminder = tempNum % 10;
        reverseNum = reverseNum * 10 + reminder;
        tempNum = tempNum / 10;
    }
    return number == reverseNum;
}

void main()
{

    for (int i = 0; i < 500; i++)
    {

        if (isPalindrome(i))
        {
            printf("%d ",i);
        }
    }
}
