At this stage, some tasks will include an additional `TestMain` method. Please ignore it and write your solution only in the `Main` method.

Note


using Xunit;
using System;
using System.IO;

namespace ConsoleApp {
    public class ProgramTests {
        [Fact(DisplayName = "Main prints something to console")]
        public void Main_PrintsAnyOutput()
        {
            var sw = new StringWriter();
            Console.SetOut(sw);
        
            Program.TestMain(Array.Empty<string>());
        
            string output = sw.ToString();
        
            Assert.False(string.IsNullOrWhiteSpace(output));
        
            Console.SetOut(new StreamWriter(Console.OpenStandardOutput()) { AutoFlush = true });
        }
