The article advocates for using stacks and queues over recursion for graph and tree traversal problems, arguing they provide better mental models and efficiency. It demonstrates with Rust code examples how iterative approaches using these data structures can be more practical and adaptable than recursive solutions, especially for real-world scenarios with constraints like user interruptions or resource limits.
Background
Recursion is commonly taught in computer science for tree and graph traversal due to its elegant mathematical properties, but it can be inefficient in practice and challenging to reason about in complex systems. Stacks and queues offer alternative approaches that can be more intuitive and performant for certain problems.
