Inside thewhile loop, the given number is divided by 10 using% (modulus) operatorand then storing theremainderin thereversenumvariable after multiplying thereversenumby 10.When we divide the number by 10, it returns the last digit as remainder.This remainder becomes the first digit ofreversenum,...
In this section, we are going to see how to reverse a number using various methods like while loop, recursion, for loop and do while loop with the help of examples. Example 1: Find Reverse Number in C++ Using While Loop Before moving to the program, let’s first understand how while l...
Inside the loop, the reversed number is computed using: reverse = reverse * 10 + remainder; Let us see how the while loop works when n = 2345. nn != 0remainderreverse 2345 true 5 0 * 10 + 5 = 5 234 true 4 5 * 10 + 4 = 54 23 true 3 54 * 10 + 3 = 543 2 true 2 54...

Let's see a simple C# example to reverse a given number. using System; public class ReverseExample { public static void Main(string[] args) { int n, reverse=0, rem; Console.Write("Enter a number: "); n= int.Parse(Console.ReadLine()); while(n!=0) { rem=n%10; reverse=reverse*...

Explanation: In the exercise above the code defines a function named "string_reverse()" that takes a string as input and returns its reversed version using a while loop and string manipulation. The final print statement demonstrates the result of calling the "string_reverse()" function with the...
So next, let’s translate this idea into Kotlin code using the division operator ‘/‘ and the modulus operator ‘%‘: fun reverseNumber(number: Int): Int { var n = number var result = 0 while (n > 0) { result = 10 * result + n % 10 n = n / 10 } return result } Next...
bash shell提供了for命令,允许你创建一个遍历一系列值的循环。每次迭代都使用其中一个值来执行已定义好的一组命令。下面是bash shell中for命令的基本格式。 1forvarinlist2do3commands4done 在list参数中,你需要提供迭代中要用到的一系列值。可以通过几种不同的方法指定列表中的值。
Number is 10 Number is 9 Number is 8 Number is 7 Number is 6 Number is 5 Number is 4 Number is 3 Number is 2 Number is 1 Using the reversed() Method with a Range You can define a range to iterate in a loop. Using the reversed() function, you can iterate the range in revers...
