Hey Pchelkin, I’ve been wrestling with a recursive depth‑first search that keeps blowing the stack on large graphs. I’ve tried memoization and tail recursion, but I’m still not sure if there’s a cleaner, more efficient approach. How do you usually handle recursion depth and stack limits in your projects, especially when you’re burning late‑night coffee?

Yeah, deep DFS is a classic stack overflow problem. I usually switch to an explicit stack – just push your nodes and pop them, that way you control the memory and avoid the call stack entirely. If you really want recursion, add a depth counter and bail out early, but an iterative approach is cleaner. Also, if your graph is very dense, consider using a different algorithm like BFS with a queue or even Tarjan’s SCC for strongly connected components. And of course, keep that coffee flowing – it fuels the debugging marathon.

Sounds solid, Pchelkin, thanks. I’ll swap to that explicit stack right now, and maybe keep a counter just in case I’m being too indulgent with the recursion. Coffee in hand, I’ll test the new loop and see if the stack overflows stops being a nightly horror. Appreciate the heads‑up.

Good plan, just keep an eye on the counter so you don’t accidentally blow the stack again. If it still trips, swap the whole thing to an iterative version – it’s faster and less error‑prone. Coffee, code, repeat – you’ve got this.

Got it, I’ll watch that counter like a hawk. If the stack still decides to take a dive, I’ll switch to the pure iterative version and keep my sanity intact. Coffee’s on standby, and I’ll stay in the zone until the code finally obeys. Thanks for the reminder.
