Sum of Two Equals Third

Write a C# Sharp program to check whether it is possible to add two integers to get the third integer from three given integers.

Visual Presentation:

Sample Solution:-

C# Sharp Code:

using System;
using System.Linq;

namespace exercises
{
    // Class declaration
    class Program
    {
        // Main method - entry point of the program
        static void Main(string[] args)
        {
            // Calling the 'test' method with different integer values and printing the results
            Console.WriteLine(test(1, 2, 3));    // Output: True
            Console.WriteLine(test(4, 5, 6));    // Output: True
            Console.WriteLine(test(-1, 1, 0));   // Output: True
            Console.ReadLine(); // Keeping the console window open
        }

        // Method to check if any two numbers among three add up to the third number
        public static bool test(int x, int y, int z)
        {
            // Returns true if any two numbers among x, y, and z add up to the third number
            return x == y + z || y == x + z || z == x + y;
        }
    }
}

Sample Output:

True
False
True
