Array of Length 2 Contains 15 or 20

Write a C# Sharp program to check if an array of integers length 2 contains 15 or 20.

Visual Presentation:

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 result of the 'test' method with different integer arrays as arguments
            Console.WriteLine(test(new[] { 12, 20 })); // Calling test method with array [12, 20] and displaying the result
            Console.WriteLine(test(new[] { 14, 15 })); // Calling test method with array [14, 15] and displaying the result
            Console.WriteLine(test(new[] { 11, 21 })); // Calling test method with array [11, 21] and displaying the result
        }        

        // Method to check if any element in the input array is equal to 15 or 20
        public static bool test(int[] nums)
        {
            // Returning true if any element in the array is equal to 15 or 20
            return nums[0] == 15 || nums[0] == 20 || nums[1] == 15 || nums[1] == 20;
        } 
    }
}

Sample Output:

True
True
False
