Basic Java Program to Reverse an int Array In this first example, we take the size of array and the elements of array as input. We consider a function reverse which takes the array (here array) and the size of an array as the parameters. Inside the function, we initialize a new array...
To reverse an integer using awhileloop, we must follow all three steps mentioned. Example: importjava.util.Scanner;publicclassReverse_While{publicstaticvoidmain(String args[]){System.out.print("Enter the Integer you want to Reverse: ");Scanner input_num=newScanner(System.in);intinput_number=...
In some cases, the Interviewer can also ask why you use that particular method and why notInteger.valueOf()so be prepared for that. If you need an answer then you can also see this article. After that, I pass that integer to our method called thereverseBits(int number)which reverse the...
In this article, we will dive into various ways to reverse a number using integer reversal. We will begin by exploring the iterative approach, which breaks down numbers into individual digits and rebuilds them in reverse order. Next, we will discuss recursion as an alternative solution. We wil...
public static String reverseString(String input) { int length = input.length(); String reversed = ""; int i = length - 1; while (i >= 0) { reversed += input.charAt(i); i--; } return reversed;}This method takes a string (input) as an argument and returns the reversed string....
On Crunchify, we have published more than 500 Java Tutorials and in this tutorial we will go over steps on how to reverse a string in Java? There are 7
return int(str(n)[::-1]) number = int(input("Enter a number: ")) print("Reversed number: ", reverse_number(number)) In this code, the functionreverse_numberuses Python’s built-in functionsstrandintto convert the input number into a string and then back into an integer. The slicing...

staticvoidMain(){int[]nums={1,2,3,4};Array.Reverse(nums);Console.WriteLine(String.Join(",",nums));}} Output: 4,3,2,1 Note: The above method modifies the original array instead of creating an array. If you don’t want to modify the original array, you can use theEnumerable.Revers...
