Python Coding challenge - Day 506| What is the output of the following Python Code?

Code Explanation:

1. from collections import deque

Purpose: Imports the deque class from Python’s collections module.

Effect: Enables usage of deque, a double-ended queue optimized for fast appends and pops from both ends.

2. d = deque([11, 12, 13, 14, 15])

Purpose: Creates a deque object d initialized with the list [11, 12, 13, 14, 15].

Effect: d is now a double-ended queue containing these elements in order.

3. d.rotate(2)

Purpose: Rotates the deque d 2 steps to the right.

Effect: The last two elements move to the front:

Before rotation: [11, 12, 13, 14, 15]

After rotation: [14, 15, 11, 12, 13]

4. print(list(d))

Purpose: Converts the deque d back into a regular list and prints it.

Effect: Outputs [14, 15, 11, 12, 13] to the console.

Final output:

[14, 15, 11, 12, 13]
