Unit 2 Session 1 (Click for link to problem statements)

Understand what the interviewer is asking for by using test cases and questions about the problem.

• What if the products list is empty?
  • In this case, return an empty list.
• What if no products need to be restocked?
  • In this case you would also return an empty list.
• What should my code do if an item quantity is exactly equal to the restock threshold?
  • In this case, consider the item stocked and do not include it in your output.

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Loop through each product, and make a list of any products with quantity below the threshold.

1) If products is empty, return an empty list 2) Restock list starts empty 3) For each product and quantity: a) If quantity < threshold, add to restock list 4) Return restock list

def get_items_to_restock(products, restock_threshold): if not products: return [] restock_list = [] for product, quantity in products.items(): if quantity < restock_threshold: restock_list.append(product) return restock_list
