Right. For the first many decades of computing, recursion was just always the wrong answer for a production software system. (Feel free to provide a counter-example, but please begin with an explanation of how the size of a call stack frame is determined and how exceeding the base allocation is handled on this platform).

So what tree-traversal/quicksort problems tend to measure is how long it's been since you last did CS class homework problems.

There's no need to put your data on the call stack.

Great. Please explain how the size of a call stack frame is determined and how exceeding the base allocation is handled on the particular platform you're proposing to recurse upon.
