Solution Review: Buy and Sell Stock

Explore methods to solve the buy and sell stock problem using arrays in Python. Understand the brute force approach with O(n²) complexity and an optimized solution tracking minimum prices for O(n) time. This lesson enables you to find the maximum profit from stock prices by applying efficient algorithmic strategies.

In this lesson, we will review the solution to the problem in the last exercise. Let’s go over the problem statement once again:

Given an array of numbers consisting of daily stock prices, calculate the maximum amount of profit that can be made from buying on one day and selling on another day.

We consider two approaches to this problem. In the first, we consider a brute force approach that solves the problem in O(N2)O(N^2) ...
