+In this article, we'll write a program that checks if a number is a palindrome or not in Kotlin.
+
+## How to Implement the Solution
+
+code for palindrome.kt:
+```kotlin
+    fun main() {
+    var n: Int
+    var num: Int
+    var digit: Int
+    var rev: Int = 0
+
+    print("Enter a positive number: ")
+    num = readLine()!!.toInt()
+
+    n = num
+
+    do {
+        digit = num % 10
+        rev = (rev * 10) + digit
+        num = num / 10
+    }while (num != 0)
+
+    if (n == rev){
+        println(true)
+    }else{
+        println(false)
+    }
+}
+
+```
+
+## How to Run Solution
+
+To run the solution to check if a number is a palindrome or not, we first create some variables we will use in the algorithm in the main function as shown here:
+```kotlin
+    var n: Int
+    var num: Int
+    var digit: Int
+    var rev: Int = 0
+ ```
+ Then we will prompt the user to input the number that needs to be checked:
+ ```kotlin
+    print("Enter a positive number: ")
+    num = readLine()!!.toInt()
+ ```
+ Then we use a do while loop to reverse the number that was typed in:
+ ```kotlin
+    do {
+        digit = num % 10
+        rev = (rev * 10) + digit
+        num = num / 10
+    }while (num != 0)
+```
+Finally, we check if the number and its reverse are the same or not. If they are the same, we tell the user that it's true, otherwise we tell the user that it's false, as shown here:
+```kotlin
+    if (n == rev){
+        println(true)
+    }else{
+        println(false)
+    }
+```

+This is an article on how to check if a number is a palindrome in every language.
+
+## Description
+
+A palindrome number is a number that reads the same backward and forward.
+Example: 343, 121, 909, 222
+
+## Requirements
+
+Create a file called "Palindrome Number" using the naming convention appropriate for your language of choice.
+Write a program that accepts an input of an integer and prints whether the number is a palindrome or not.
+
+## Testing
+The following table contains various test cases that you can use to verify the correctness of your solution:
+
+| Description                  | Input | Output |
+|------------------------------|-------|--------|
+| no input                     | None  | Usage: please input a number |
+| empty input                  | ""    | Usage: please input a number |
+| invalid input: not a number  | a     | Usage: please input a number |
+| sample input: palindrome     | 232   | true       |
+| sample input: not palindrome | 521   | false   |
