# Method name: print_pyramid
# Input: a number n
# Returns: Nothing
# Prints: a pyramid consisting of "*" characters that is "n" characters tall
#         at its tallest
#
# For example, print_pyramid(4) should print

# This is how we require the print-triangle.rb file in the current folder.
# We can now use the "print_triangle" and "print_line" methods we defined
# there -- as if we defined them here!

require_relative "./print_triangle"

def print_pyramid(height)
  # This is your job. :)
  # Suggestion: you can call print_triangle to print out the first, "upward"
  # half of the pyramid. You'll have to write code to print out the second,
  # "downward" half of the pyramid.

  print_triangle(height)
  height.downto(1) do |i| # or, equivalently, reverse the range from height to 1
    print_line(i) # I called the print_line method to repeat the same process as in print_triangle.rb
