A nested list is a list that contains other lists as its elements.
Nested lists can be created using square brackets and separating the elements with commas.
Elements of a nested list can be accessed using indexing and slicing.
Example: my_list = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
Accessing element 5: my_list[1][1]
A queue is a data structure that follows the First In First Out (FIFO) principle.
Elements are added to the back of the queue and removed from the front.
Example: A line of people waiting for a movie ticket.
Operations: Enqueue (add element to back), Dequeue (remove element from front), Peek (view front element)
