10 as First or Last Element in Array

Write a C# Sharp program to check a given array of integers of length 1 or more. Return true if 10 appears as either the first or last element in the given array.

Sample Solution:-

C# Sharp Code:

using System;

namespace exercises
{
    class Program
    {       
        // Entry point of the program
        static void Main(string[] args)
        {
            // Calling the test method with different integer arrays and printing the results
            Console.WriteLine(test(new[] { 10, 20, 40, 50 }));
            Console.WriteLine(test(new[] { 5, 20, 40, 10 }));
            Console.WriteLine(test(new[] { 10, 20, 40, 10 }));
            Console.WriteLine(test(new[] { 12, 24, 35, 55 }));

            // Keeps the console window open until a key is pressed
            Console.ReadLine();
        }

        // Method to check if the first or last element of the array is equal to 10
        public static bool test(int[] nums)
        {
            // Returns true if the first element is equal to 10 or the last element is equal to 10
            return nums[0] == 10 || nums[nums.Length - 1] == 10;
        } 
    }
}

Sample Output:

True
True
True
False
