C#: Check two given arrays of integers of length 1 or more and return true if they have the same first element or they have the same last element

C# Sharp Basic Algorithm: Exercise-90 with Solution

Write a C# Sharp program to check two given arrays of integers of length 1 or more. Return true if they have the same first element or the same last element.

Sample Solution:-

C# Sharp Code:

using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
    class Program // Defining a class named 'Program'
    {
        static void Main(string[] args) // The entry point of the program
        {
            // Output the results of the 'test' function with different pairs of integer arrays as arguments
            Console.WriteLine(test(new[] { 10, 20, 40, 50 }, new[] { 10, 20, 40, 50 })); // Calling test method with arrays [10, 20, 40, 50] and [10, 20, 40, 50] and displaying the result
            Console.WriteLine(test(new[] { 10, 20, 40, 50 }, new[] { 10, 20, 40, 5 })); // Calling test method with arrays [10, 20, 40, 50] and [10, 20, 40, 5] and displaying the result
            Console.WriteLine(test(new[] { 10, 20, 40, 50 }, new[] { 1, 20, 40, 5 })); // Calling test method with arrays [10, 20, 40, 50] and [1, 20, 40, 5] and displaying the result

            Console.ReadLine(); // Waiting for user input before closing the console window
        }

        // Method to check if the first element of one array matches the first element of another array
        // or if the last element of one array matches the last element of another array
        public static bool test(int[] a1, int[] a2)
        {
            // Returns true if the first element of 'a1' matches the first element of 'a2'
            // or if the last element of 'a1' matches the last element of 'a2'
            return a1[0] == a2[0] || a1[a1.Length - 1] == a2[a2.Length - 1];
        }
    }
}

Sample Output:

True
True
False
