Stock trading with cooldown

CodingAlgorithms & data structuresMid–Senior~25 min

Given daily prices of a stock, you may complete as many buy/sell transactions as you like, but you can hold at most one share at a time and after you sell you must wait one full day (cooldown) before buying again. Return the maximum profit. The price list may be empty.

What a strong answer looks like

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
