Every function call adds a frame to the call stack. Each frame stores local variables, return addresses, and execution context. With recursion, this becomes a problem fast.

Recursion occurs when a function calls itself to solve a problem by breaking it down into smaller subproblems. In Scala, recursion is the preferred approach over imperative loops for many algorithms,…
