Type · algorithmic
Given a list of daily sales transactions for a set of small retail stores, write a function to calculate the total sales for each store and identify the top 3 performing stores for a given month. Assume transactions are in a list of dictionaries, each with 'store_id', 'timestamp', and 'amount'. - 3
Type · algorithmic
Implement a function that takes a list of product IDs and their inventory levels, and another list of customer orders (product ID and quantity). The function should return a list of orders that can be fulfilled based on available inventory, updating the inventory levels accordingly. Handle cases where an order partially exceeds inventory. - + 1 more questions in this round (sign up to unlock)
