Solution

The data structure used for implementing recursion is the Stack.

Here's a step-by-step explanation:

  1. When a recursive function is called, the computer stores a snapshot of the function, including the variables, the place it was called from, and where to return to (known as the context), on the stack.

  2. If the recursive function is called again before the first function call is finished, another snapshot is stored on the stack.

  3. This process continues until the base case is reached.

  4. Once the base case is reached, the computer starts unwinding the stack, going back through the snapshots and completing each function call.

  5. This process continues until the stack is empty, meaning all recursive function calls have been completed.

So, the stack data structure is used to manage and keep track of recursive function calls.
