Which data structure is used for implementing recursion?QueueStackArrayList

The data structure used for implementing recursion is Stack.

Here's why:

1. Recursion involves the concept of "Last-In, First-Out" (LIFO). This means that the last function call is the first one to be executed and returned.

2. A Stack follows the LIFO concept. It is a data structure where the last element added is the first one to be removed.

3. When a recursive function is called, the computer stores a stack frame with the variables for that call on the stack. This frame includes any parameters and local variables.

4. When the recursive call is finished, the computer uses the stack to remember where it was in the previous call. It pops the stack frame for the current call off the stack, and resumes where it left off in the previous call.

5. Therefore, the Stack data structure is used for implementing recursion.

The data structure used for implementing recursion is Stack.

Here's why:

1. Recursion involves the process of a function calling itself while solving a problem. This self-calling mechanism follows the principle of Last-In-First-Out (LIFO), which is the fundamental concept of a Stack.

2. When a recursive function is called, the system stores the memory address, the return address, and the local variables of the calling function on the stack.

3. When the called function finishes execution, it returns control to the calling function, and its memory is subsequently cleared from the stack.

4. This process continues until the base condition is met, and all the stacked-up function calls are completed.

5. Therefore, the Stack data structure is used to manage these function calls in recursion.
