Thank you TALESRA .nice explanation in detail and walking through step by step of the code at the last several minute ! what about using Deque in this question ? It would nice if if record video as deque for this question .

[saiavinashduddupudi]

Wonderful explanation! Thanks :)
Althought the entire space complexity narrows down to O(n), I see that you are utilizing 2 queues - Don't you think we can eliminate next_queue and handle everything in queue=[] itself by popping the visited nodes?

Hi TALESRA, thank you for the great and clear explanation.
I want to ask you how do you come out with this solution? And why do you name the variables queue and next_queue?
Thank you for reading my questions!
