C# Sharp Basic Algorithm: Exercise-61 with Solution

Write a C# Sharp program to insert a given string into the middle of another given string of length 4.

Sample Solution:-

C# Sharp Code:

using System; // Import the System namespace which contains fundamental types and base classes
using System.Collections.Generic; // Import the System.Collections.Generic namespace for collections
using System.Linq; // Import the LINQ namespace for LINQ functionality
using System.Text; // Import the System.Text namespace for string manipulation
using System.Threading.Tasks; // Import the System.Threading.Tasks namespace for asynchronous operations

namespace exercises // Define a namespace called 'exercises'
{
    class Program // Define a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {
            // Output the result of test function with two strings as arguments
            Console.WriteLine(test("[[]]", "Hello")); // Test with strings "[[]]" and "Hello"
            Console.WriteLine(test("(())", "Hi")); // Test with strings "(())" and "Hi"
            Console.ReadLine(); // Wait for user input before closing the console window
        }

        // Function definition of test function that takes two strings 's1' and 'word' and returns a string
        public static string test(string s1, string word)
        {
            // Concatenates a substring of s1 (from index 0 to index 2 exclusive) with the 'word' and then concatenates the rest of s1 (from index 2 onwards)
            return s1.Substring(0, 2) + word + s1.Substring(2);
        }
    }
}

Sample Output:

[[Hello]]
((Hi))

Previous: Write a C# Sharp program to create a new string using two given strings s1, s2, the format of the new string will be s1s2s2s1.
Next: create a new string using three copies of the last two character of a given string of length at least two.
