Implementation of Deque by Circular Array

Implementation of Deque by Circular Array is a DSA topic. In plain words you use it for a short Implementation of Deque by Circular Array example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Implementation of Deque by Circular Array example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Implementation of Deque by Circular Array.

From the example next to this theory — Implementation of Deque by Circular Array — queue is FIFO.

Trap: only saying “Implementation of Deque by Circular Array” with no example. Fix that before you talk about advanced DSA.

Viva: what is Implementation of Deque by Circular Array? Then show the smallest Implementation of Deque by Circular Array example you can type. Then name the trap.

  array → [10,  20,  30]

Exam tip

What is Implementation of Deque by Circular Array? Show this: the smallest Implementation of Deque by Circular Array example you can type. Trap: only saying “Implementation of Deque by Circular Array” with no example.

Example

from collections import deque

q = deque()
q.append(10)      # enqueue
q.append(20)
print(q.popleft())  # 10
print(list(q))

Implementation of Deque by Circular Array — queue is FIFO. deque.popleft() is O(1).
