kotlin 判断数字

Given an integer number, we have to find reverse number and print it.

给定一个整数，我们必须找到反向数字并打印出来。

**Example:**

**例：**

Input:
        Number: 12345
    
        Output:
        Reverse Number: 54321

**To find a reverse number** – we use this formula: ***reverse = (reverse \* 10) + lastDigit***, to calculate the ***lastDigit***, we find the remainder of the number by dividing the number with 10.

**要找到一个反向数字** –我们使用以下公式： ***reverse =(reverse \* 10)+ lastDigit*** ，要计算***lastDigit*** ，我们可以通过将数字除以10来找到数字的余数。

Consider the below program to **find the reverse number**.

考虑下面的程序以**找到反向编号** 。

### 计划在Kotlin中反转数字 **(**Program to reverse a number in Kotlin**)** ###

package com.includehelp.basic
    
    import java.util.*
    
    /* Function to Reverse an given Integer Number */
    fun getReverse(number: Int): Int {
        var number = number
        var sum = 0
        
        while (number > 0) {
            val r = number % 10
            sum = sum * 10 + r
            number /= 10
        }
        return sum
    }
    
    
    //Main function Entry Point of Program
    fun main(arg: Array<String>) {
        val sc = Scanner(System.`in`)
        
        //Input Number
        println("Enter Number  : ")
        val num: Int = sc.nextInt()
        
        //Calling function to get reverse number
        val reverseNumber = getReverse(num)
        
        // Print reverse format of number
        println("Reverse Number : $reverseNumber")
    }

**Output**

**输出量**

Run 1:
    Enter Number  :
    12345
    Reverse Number : 54321
    -------
    Run 2:
    Enter Number  :
    345389
    Reverse Number : 983543
