Hello Irfan,
So we are using recursive approach here, and under the hood recursion uses Stack. If we go through iteratively, then we have to have an array.
So ultimately I'm using one another data structure here.
So can I ask it to interviewer like what is the point to do this whole stuff when I can easily do it??

I really like the recursion that Irfan used while implementing the solution, I'd come up with a cycle that pops and pushes the elements until it reaches the first element.
