Question
What data structure from the following is used for implementing recursion?OptionsArrayStackListQueue
Solution
The data structure used for implementing recursion is Stack.
Here's why:
-
Recursion involves a function calling itself while some condition is true and it needs a way to remember the previous states.
-
In a recursive function, when a new function is called, it gets added on top of the previous function call.
-
When a function finishes its operation, it needs to return to the function that called it. This follows the Last In First Out (LIFO) principle, which is the main characteristic of a Stack.
-
Therefore, the system uses a 'Call Stack' to keep track of function calls.
So, the Stack is the data structure used for implementing recursion.
