Data Structures for Coding Interviews in Java

Solution: Implement Depth-First Search

Explore how to implement depth-first search for directed graphs starting from a source vertex. This lesson helps you understand the traversal process, manage visited nodes to avoid cycles, and analyze time and space complexity, equipping you to handle graph traversal tasks in coding interviews.

We'll cover the following...

Statement

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

Constraints

  • 11 ≤\leqgraph.length ≤\leq10310^3

  • ...
