# Kotlin Program to Check Number is Palindrome or Not

Write a Kotlin Program to Check a given number is palindrome or not.

For example,

``` Input:
1122

Output:
1122 is not palindrome
```
``` Input:
12321

Output
12321 is palindrome
```

## 1. Program to Check Whether Number is Palindrome

Sourcecode –

```import java.util.*

fun main() {

println("Enter n:")

val origN = n
var reverseN = 0
while (n != 0) {
val remainder = n % 10
reverseN = reverseN * 10 + remainder
n /= 10
}

val result = if(reverseN == origN) "\$origN is palindrome" else "\$origN is not palindrome"
println(result)
}

```

When you run the program, output will be –

```Enter n:
32324
32324 is not palindrome
```
###### Explanation:

We can check whether number is palindrome or not by comparing original and it’s reversed number.

For example,
Let’s assume n = 123.
It’s reversed number will be 321.
Since 321 is not equal to 123, 123 is not palindrome.

Let’s take another example,
n = 12321
It’s reversed number will be 12321.
Since 12321 (original) is equal to 12321 (reversed number), 12321 is palindrome.

In our program, we

– stored original number in variable origN
– reversed n and stored it in variable reverseN

Then, we compared origN and reverseN to check for palindrome

Thus, we went through Kotlin Program to check number is palindrome or not.
