Reverse a string using Split, Reverse, Join In this first method, we'll use JavaScript's built-in split, reverse, and join methods to reverse the string. const str = 'hello world!'; // step 1: const strChunks = str.split(""); console.log(strChunks); // Output: ["h", "e",...
The code above results in: The original string is: guitar The reversed string is: ratiug Using a for Loop to Reverse the String With a for loop, we can iterate over each character from the string. Starting from the end of the string to the beginning of the string - we can continuous...

var variablename1 = [...value];Code language: JavaScript (javascript) Approach 3 – Using reduce() function for reverse Use the spread operator to convert the string into an array of characters. Use reduce() function in JavaScript to make a reverse string from an array by concatenating the...
Reverse string using for loop a = 'Python' b = '' for c in a: b = c + b print(b) # nohtyP Reverse the string using recursion There are many ways to reverse a string using recursion. In the presented method, the recursive function copies the last character of the string to the ...
= 0 fails and while loop exits. reversed already contains the reversed number 4321. Example 2: Reverse a number using a for loop in Java class Main { public static void main(String[] args) { int num = 1234567, reversed = 0; for(;num != 0; num /= 10) { int digit = num % ...
Original num_array: 1,2,3,4,5 Original string_array: Reversed num_array: 5,4,3,2,1 Reversed string_array: JavaScript,Python,Java Reversing an Array with a for Loop Finally, the good old way is to simply run the array through a for loop in backwards order, and add each element in...
How can you loop over an iterable in reverse?Reversing sequences with slicingIf you're working with a list, a string, or any other sequence in Python, you can reverse that sequence using Python's slicing syntax:>>> colors = ["purple", "blue", "green", "pink", "red"] >>> colors...
In this code, we’ve implemented a concise string reversal function namedStringReverse. We use aforloop to iterate over each character in the input string. Within the loop, we prepend each character to theResultString, effectively reversing the order of the characters. The main function showcase...
Use thewhileLoop to Reverse an Integer in Java 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 ...
