Which data structure would you use to implement a recursive algorithm iteratively?
Step 1: Understand what a recursive algorithm is. A recursive algorithm calls itself to solve smaller parts of a problem.
Step 2: Realize that recursion uses a call stack to keep track of function calls and local variables.
Step 3: To implement the same logic without recursion, you need a way to keep track of these calls and variables manually.
Step 4: A stack data structure is perfect for this because it follows the Last In, First Out (LIFO) principle, just like the call stack in recursion.
Step 5: Use the stack to push function parameters and local variables when you 'call' the function, and pop them off when you 'return' from the function.
