Problem Overview

Given an array of stock prices where prices[i] represents the price on day i, find the maximum profit by buying on one day and selling on a future day. If no profit is possible, return 0.

🎯 Solution Approach

In this video, I walk through solving this classic dynamic programming problem using Swift. The key insight is tracking the minimum price seen so far while calculating the maximum profit at each step.
Time Complexity: O(n) - Single pass through the array
Space Complexity: O(1) - Only using constant extra space

📝 Examples Covered

Example 1: prices = [7,1,5,3,6,4] → Output: 5
Example 2: prices = [7,6,4,3,1] → Output: 0
