Is it possible to get more detailed feedback on these queue questions?

I am getting Unknown Error - Check your Input

I don't know what type queue is, so I tried printing it to see if it is of type Node or if it is a list in order to begin working through this problem.

I want some clarity on what implementation of a Queue we should expect to see in the problem set. In the first problem the queue is implemented as a list, in Python.

It was not clear that the front of the 'queue' should be the 0 index of the list?

Why show a Queue that uses Node and .next, .enqueue, .dequeue functions if these are not used?

In a real interview leetcode/hackerrank/coderpad what approach should we use?

However... this doesn't have them and uses arrays instead. What is the point of teaching stacks and queues?

Why are we using peek() instead of remove() and pop() ?
