        	// output: Cara earns the highest salary of $65000.

        // Same thing, but a single line of LINQ
		var winner = emps.OrderByDescending(emp => emp.Salary).First();
		Console.WriteLine($"{winner.Name} earns the highest salary of ${winner.Salary}.\r\n");
			// output: Cara earns the highest salary of $65000.

        // If we don't care about who, our LINQ gets even shorter
		Console.WriteLine($"The highest salary is ${emps.Max(emp => emp.Salary)}.\r\n");
        	// output: The highest salary is $65000.
	}

public class Employee

	public int Age { get; set; }
	public decimal Salary { get; set; }
	public string Gender { get; set; }
