  Where did Person get the spoon from?

  Write a table that lists the furniture and other large items that appear in each room. The table should list the name of the item, the room it appears in, its approximate size, and its other attributes.

  Then, create another table that lists the small items that appear in each room. [snipped the rest of the prompt for brevity]

  Item Room Size (LxWxH, cm) Attributes

  Sofa Living room 200x90x85 3-seater, upholstered, with cushions

  Coffee table Living room 100x60x45 Wooden, rectangular

  TV Living room 120x6x70 Wall-mounted, flat-screen, 55 inches

  Refrigerator Kitchen 70x70x170 Stainless steel, 300L capacity

  Cushions Living room Sofa 45x45x15 Soft, decorative

  Remote control Living room Coffee table 15x5x2 For TV

  Vase Living room Coffee table 15x15x30 Glass, decorative

  Flowers Living room Vase Varies Fresh or artificial

  I want you to simulate the classic program SHRDLU by Terry Winograd. SHRDLU functions like above. You will simulate both "Person" and "Computer". "Person" will move around the apartment, pick up a coaster, move to the kitchen, and put the coaster on the kitchen island. After each action of "Person", "Computer" will give one sentence describing the position of the most-recently changed objects.

  Continue to simulate SHRDLU. "Person" goes through the stages to make a cup of tea. There is a bottle of milk in the refrigerator. At each step of the simulation, include "Person"'s thoughts in curly brackets, { }. See the example below. [Example snipped]

  # n : an integer n > 3, no upper limit
  # seed : an optional integer parameter (default = 1) for the polynomial function
  # pollards_rho(n, seed) : an integer or nil, representing a non-trivial factor of n, or nil if the algorithm fails to find a factor

  def pollards_rho(n, seed = 1)
  return n if n <= 3

  x = 2
  # x : an integer, initially set to 2, will be updated using the polynomial function f
  # x will always be in the range [0, n)

  y = 2
  # y : an integer, initially set to 2, will be updated using the polynomial function f
  # y will always be in the range [0, n)

  d = 1
  # d : an integer, initially set to 1, will store the greatest common divisor of (x - y) and n
  # 1 <= d <= n

  while d == 1
    x = f(x, n, seed)
    # x : updated using the polynomial function f, x = (x * x + seed) % n
    # x will always be in the range [0, n)

    y = f(f(y, n, seed), n, seed)
    # y : updated using the polynomial function f twice, y = ((y * y + seed) * (y * y + seed) + seed) % n
    # y will always be in the range [0, n)

    d = gcd((x - y).abs, n)
    # d : the greatest common divisor of the absolute difference between x and y, and n
    # 1 <= d <= n, such that (x - y) % d == 0 and n % d == 0
  end

  d == n ? nil : d
  # Returns a non-trivial factor of n (1 < d < n) if one is found, or nil if the algorithm fails to find a factor
