Implementation of Deque by Circular Array

Amit only reaches for Implementation of Deque by Circular Array when a Implementation of Deque by Circular Array dry-run has to stay correct in a small live site.

Keep Implementation of Deque by Circular Array small. Amit should finish a Implementation of Deque by Circular Array dry-run in a few lines, not a 40-line dump.

Skip Implementation of Deque by Circular Array and skipping the failure case for Implementation of Deque by Circular Array shows up in a small live site.

Use Implementation of Deque by Circular Array when a Implementation of Deque by Circular Array dry-run must stay clear. If a simpler DSA step works, use that instead.

Don’t do this with Implementation of Deque by Circular Array: skipping the failure case for Implementation of Deque by Circular Array. Interviewers spot it in ten seconds.

After Implementation of Deque by Circular Array, Amit should still remember skipping the failure case for Implementation of Deque by Circular Array.

Close Implementation of Deque by Circular Array with: “If I skip it, a Implementation of Deque by Circular Array dry-run goes wrong like this: skipping the failure case for Implementation of Deque by Circular Array.”

Exam tip

For Implementation of Deque by Circular Array: definition + a small live site + one failure.

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).

Short notes
