Question
What data structure would you mostly likely see in non recursive implementation of a recursive algorithm?
Options
- Stack
- Linked List
- Tree
- Queue
Solution
The data structure you would most likely see in a non-recursive implementation of a recursive algorithm is a Stack.
Here's why:
-
A recursive algorithm involves a function calling itself while a certain condition is true. This process can be visualized as a stack of calls, where each call is waiting for the calls below it to complete.
-
When a recursive algorithm is converted to a non-recursive one, this "call stack" is often simulated using a Stack data structure.
-
The Stack data structure follows the Last-In-First-Out (LIFO) principle, which aligns with the execution order of a recursive algorithm. The last function call made is the first one to finish execution.
-
While Linked Lists, Trees, and Queues can also be used in certain scenarios, the Stack is the most common data structure used for this purpose.
