One of Two Integers in Range 20-50

Write a C# Sharp program to check whether two given integer values are in the range 20..50 inclusive. Return true if one or other is in the range, otherwise false.

Sample Solution:

C# Sharp Code:

using System;

// Namespace declaration
namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
			// Displaying the results of the 'test' method with different pairs of integers
            Console.WriteLine(test(20, 84)); // Output: True
            Console.WriteLine(test(14, 50)); // Output: True
            Console.WriteLine(test(11, 55)); // Output: False
            Console.WriteLine(test(25, 40)); // Output: True
            Console.ReadLine();
        }

        public static bool test(int x, int y)
        {
            // Check if either x or y is within the range 20 to 50 inclusive
            return (x >= 20 && x <= 50) || (y >= 20 && y <= 50);
        }
    }
}

Sample Output:

True
True
False
True

Explanation:

The condition checks if x is between 20 and 50 inclusive: (x >= 20 && x <= 50).
It also checks if y is between 20 and 50 inclusive: (y >= 20 && y <= 50).
The logical OR (||) ensures that if either of these conditions is true, the method returns true.

Test Cases and Results:

test(20, 84) returns True because 20 is in the range 20 to 50.
test(14, 50) returns True because 50 is in the range 20 to 50.
test(11, 55) returns False because both 11 and 55 are outside the range of 20 to 50.
test(25, 40) returns True because both 25 and 40 are within the range 20 to 50.
