the issue with recursion is that it takes up a lot of space on the stack a better way to do it is using a queue system that stores all the points that need to be checked, then do what you need with each of those. that way you only have one bit of code trying to run at a time vs waiting for a ton of functions to complete. i've found that you can reach recursion limits very quickly with recursion flood fill

[@DuskyDaily]

A queue also takes up space, xD. Still O(M*N) space, both for using a stack or a queue. For recursion limit problem, use a custom stack then, since stacks are marginally faster than queues while growing.

6:39 Bro we can use queue as well. Just push the source coordinates and then push its neighbouring coordinates into the queue after taking source out and so on. Time complexity will also be the same. Infact, we can use any from both stack and queue because LIFO and FIFO doesn't matter in this question as we only have to colour the matrix. Space complexity will also be the same in both dfs and bfs because in dfs you are also using recursive stack space

[@berni303]

You're absolutely correct, and I lean towards BFS over DFS for this particular problem. I'm a bit surprised the author wasn't aware that BFS performs just as effectively in this context.

[@ThePeteyGG]

Yup, bfs and dfs are usually interchangeable in these interview questions. And since a queue is pretty much just a linked list, the one student that suggested that was also incorrectly marked as wrong. You can get bonus points for mentioning that depending on the structure of the data one may be slightly better than the other for amount of space they take up, but generally big O they are the same. FAANG SWE here btw.

[@aaravgulati2]

@@ThePeteyGG I don't think so mentioning linked list is a wise decision( although queues can be implemented using linked list )because it's just not intuitive and will just make the code lengthy. By this logic, even array would be correct answer
