PS4 FAQ

• Can I have a hint on problem 2?

  Given that runtime, what kinds of algorithms should you be considering? Which of those algorithms is the "most natural", given the properties you're dealing with?

• Clarifications on problem 4.

  You don't actually want to create the dates, just figure out the relative order.

  Make sure you put the runtime in terms of the given problem's input, not what you convert the original problem into.
