Solution: Implement Depth-First Search

Explore how to implement a depth-first search algorithm for directed graphs using an adjacency list representation. Learn to traverse each branch deeply while managing visited nodes to avoid cycles. Understand the use of stacks and boolean arrays in tracking traversal, and analyze the algorithm's time and space complexities.

We'll cover the following...

Statement

Given a directed graph represented by an adjacency list graph and an integer source, representing the start vertex of the graph, return a list of integers, result that shows the order of depth-first traversal starting from the specified source vertex.
