U-nderstand

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.

P-lan

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
