Clear explanation. Good job!!!

[@AdeshPaul]

Thanks for teaching.

[@sujan_kumar_mitra]

explained nicely.thanks

[@sangarshlakshya]

[@ShivamYadav-in2jg]

good explanation of deque Thanks !!!!

[@sayanbanerjee2229]

Such a soothing voice, I really understood it better! Thanks!

[@deepanshuchauhan4532]

Can you tell me the condition in input restricted dequeue and output restricted dequeue of overflow and underflow

[@AjaySharma-zs8ex]

Thank you.

[@yvmoksha]

For 1 one element delete operation by any way front or rear, in any index position values when front==rear , resetting both to -1, which implies empty queue.

[@vivekvijay8763]

your videos are very good and able to understand very much. why did you stop posting videos

[@Akash-dd6ev]

Thank u

[@madhanmanohar8490]

Every thing is fine, could you please make video on #Hashing.

[@netizenbudiman6768]

what if they have 5 index?

[@wonderfulvamsi]

It's good........I wonder how u managed to not get any shadows of ur hands on the paper

[@r.kapilkumar1584]

I think she turned off shadow in settings, just like PUBG 🙄

[@rupeshpatil5147]

it will be better if you start with empty queue

[@amitbudhiraja4135]

in the last case why we setted the value of r and f to -1--------------we can set it to 0

[@sayanbanerjee2229]

No cause 0 will mean that the 0th index has a value, which is wrong, so we set it to something not in the array index.

[@sanjayroy219]

Madam please provide complete Java program

[@MO-fg2cm]

ISE people !!

[@BSEss]

Hello ma'am, in the last case where f > r, i think we can keep on using the queue, because as per your explanation, if f = 2, adding from front will add an element at index:1 and adding an element from rear will add an element at index: 2. Making f again < r. 🙂

Beautiful hand writing 🥳

[@abhishekpawar5804]

Your voice is too cute😍

[@Rahul-nk4vf]

legends look at left hand ring finger....😜😜

[@surajtopal455]

😔😔not useful , because there are more condition to implement the dequeue .

[@atharvasalpekar204]

If you already know all the things. Then why the fuck you are even watching this video at first place. Oversmart 🙄
