3573. Best Time to Buy and Sell Stock V | Leetcode Daily - Python
Dive into the advanced Best Time to Buy and Sell Stock V LeetCode problem where we tackle the unique twist of short selling! In this daily coding tutorial, we break down how to maximize profit with at most k transactions, allowing for both normal long positions (buy low, sell high) and short positions (sell high, buy low). We start with a recursive Memoization Search approach to understand the state transitions between holding nothing, holding stock, and shorting. Then, we optimize the solution using iterative Dynamic Programming (DP) with a rolling array to achieve O(nk) time complexity and O(k) space complexity. Whether you use Python, Java, C++, or JavaScript, this video provides full code solutions and a step-by-step logic breakdown to help you crush your next technical interview.
