Solution: Best Time to Buy and Sell Stock II

Explore how to apply a greedy algorithm to maximize profit in stock trading by buying and selling multiple times. Understand how accumulating gains from consecutive price increases yields optimal results, and learn to implement this approach efficiently with an O(n) time complexity solution.
