Lambda Expression

public void Linq35()
{
    string[] digits = { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" };
    var sortedDigits = digits.OrderBy(digit => digit.Length).ThenBy(digit => digit);
 
    Console.WriteLine("Sorted digits:");
    foreach (var d in sortedDigits)
