实现字符串反转

你可以使用各种编程语言来实现这个功能。以下是几种不同语言的示例：

1. Python:

def reverse_string(input_string):
    return input_string[::-1]

2. JavaScript:

function reverseString(inputString) {
    return inputString.split('').reverse().join('');
}

3. Java:

public class Main {
    public static void main(String[] args) {
        String inputString = "hello";
        String reversedString = reverseString(inputString);
        System.out.println(reversedString); // Outputs "olleh"
    }

    public static String reverseString(String inputString) {
        return new StringBuilder(inputString).reverse().toString();
    }
}

4. C#:

using System;
using System.Text;

class Program
{
    static void Main()
    {
        string inputString = "hello";
        string reversedString = ReverseString(inputString);
        Console.WriteLine(reversedString); // Outputs "olleh"
    }

    static string ReverseString(string inputString)
    {
        StringBuilder sb = new StringBuilder(inputString);
        return sb.Reverse().ToString();
    }
}
