Is recursion better than iterative?
If time complexity is the point of focus, and number of recursive calls would be large, it is better to use iteration. However, if time complexity is not an issue and shortness of code is, recursion would be the way to go….Javascript.

Why recursive function sometimes is more preferable than iterative approach?
PROS: Recursion can reduce time complexity. If you calculate the fibonacci sequence up to a number n using recursion rather than iteration, the time to complete the task when compared to that of the iterative approach was much greater.
What is recursion and how does it compare to using an iterative approach?
The concept of Recursion and Iteration is to execute a set of instructions repeatedly. The difference between them is that recursion is simply a method call in which the method being called is the same as the one making the call while iteration is when a loop is repeatedly executed until a certain condition is met.
Why is recursion more efficient than iterations?
The recursive function runs much faster than the iterative one. The reason is because in the latter, for each item, a CALL to the function st_push is needed and then another to st_pop . In the former, you only have the recursive CALL for each node. Plus, accessing variables on the callstack is incredibly fast.
When we should use recursion instead of loop and why?
Recursion is made for solving problems that can be broken down into smaller, repetitive problems. It is especially good for working on things that have many possible branches and are too complex for an iterative approach. One good example of this would be searching through a file system.
What is the advantage of recursion over iterative approach Mcq?
1. What is the advantage of recursive approach than an iterative approach? Explanation: A recursive approach is easier to understand and contains fewer lines of code.
What are the advantages of recursion in Python?
Advantages of Python Recursion
- Reduces unnecessary calling of function, thus reduces length of program.
- Very flexible in data structure like stacks, queues, linked list and quick sort.
- Big and complex iterative solutions are easy and simple with Python recursion.
