Questions
See it in action
Which data structure uses LIFO (Last In, First Out) ordering?
Why does a stack overflow happen with deep recursion?
Each recursive call reserves its own slice of the call stack. Go deep enough — say, recursion with no base case — and you run out of that reserved memory. Think of it like plates stacking up until the table gives way.
