Algorithms You Should Know

Tree Search

Tree search techniques are crucial for efficiently navigating data structures like binary trees. Alan Underwood emphasizes the importance of understanding these algorithms, especially for technical interviews with big tech companies 1. Balancing trees is a significant aspect, as unbalanced trees can degrade performance. Joe Zack explains that maintaining a balanced tree is essential to avoid turning it into a linear structure, which would be inefficient 1.

   

Graph Traversal

Graph traversal strategies, such as depth-first and breadth-first search, are fundamental in navigating complex data structures. Joe Zack uses the analogy of a family tree to explain these methods, where depth-first explores as far down one path as possible before backtracking, while breadth-first examines all nodes at the current level before moving deeper 2. He notes that depth-first search is often preferred for its simplicity in certain scenarios, though it may require additional storage to track paths in graphs with cycles 3.
