// Main method - entry point of the program
static void Main(string[] args)
{
// Calling the 'test' method with different integers and printing the results
Console.WriteLine(test(3));   // Output: True
Console.WriteLine(test(7));   // Output: True
Console.WriteLine(test(8));   // Output: True
Console.WriteLine(test(21));  // Output: False
Console.ReadLine(); // Keeping the console window open
}

// Method to check if the last digit of a number is less than or equal to 2 or greater than or equal to 8
public static bool test(int n)
{
// Returns true if the last digit of 'n' is less than or equal to 2 OR greater than or equal to 8
