Reverse a String

1. Write a program to reverse a string.

 
using System;

class Program
{
    static void Main()
    {
        string input = "hello";
        char[] charArray = input.ToCharArray();
        Array.Reverse(charArray);
        string reversed = new string(charArray);

        Console.WriteLine("Reversed string: " + reversed);
    }
}

• Convert string to a char[].
• Use Array.Reverse().
• Recreate the string.

 
using System;

class Program
{
    static void Main()
    {
        string input = "hello";
        string reversed = "";

        // Traverse string from end to start
        for (int i = input.Length - 1; i >= 0; i--)
        {
            reversed += input[i];
        }

        Console.WriteLine("Reversed string: " + reversed);
    }
}

• Start with an empty string - reversed.
• Loop from the last character (input.Length - 1) down to the first.
• Append each character to reversed.
• Finally, print the reversed string
