Type · coding
Given a list of customer transactions (each with an account ID, timestamp, and amount), write a function to calculate the daily spending limit for each account. Assume a daily limit of 10,000 DKK, and transactions exceeding this limit should be flagged. Handle potential edge cases like missing timestamps or invalid amounts.
3
Type · coding
Implement a function that takes a list of stock prices for a given day (represented as a list of tuples: (timestamp, price)) and returns the maximum profit that could have been made by buying and selling the stock once. If no profit can be made, return 0. Assume prices are in ascending order of timestamp.
