Python Program to Reverse a String Without using Recursion

This Python program reverses a given string without using recursion. It uses a simple iterative approach to reverse the string.

In this block, we present a Python program to reverse a given string without using recursion. This alternative method provides an efficient solution for reversing strings, avoiding potential performance issues and stack overflow errors.

Problem statement

Write a Python program that reverses a given string without using recursion. The program should take a string as input and output the reversed version of the string.

Python Program to Reverse a String Without using Recursion

def reverse_string(input_str):
    reversed_str = ""
    for char in input_str:
        reversed_str = char + reversed_str
    return reversed_str

# Test the function
user_input = input("Enter a string: ")
reversed_input = reverse_string(user_input)
print("Reversed String:", reversed_input)
