\# Problem 3 def get_missing_parts(goal, inventory): \# Your code here \# Problem 4 \# Your code here Your code for this assignment must use dictionaries as described. No credit will be given for importing modules specifically designed to work with multisets. 3. (8 points) Suppose you have an inventory of LEGO parts, and you want to determine if you have the right parts to build a certain goal model. Write a function get.missing-parts (goal, inventory) that returns a dictionary containing all extra parts that need to be added to inventory to build the goal. If no extra parts are needed (i.e., if goal is a multisubset of inventory), the function returns an empty dictionary. You may assume that goal and inventory are dictionaries as described earlier. The returned dictionary should be built the same way
