dude u just made me learn queues and stacks in 4 mins

[@aryanverma7800]

yes but not from interview point of view

[@shubham.papnai]

Please continue making more on c++, ur making things crystal clear, short and simple.

[@gurunarayana1382]

your tutorials are awsome but can you work on the audio its too low

[@amur_]

I have a doubt. For Competitive Programming, Do we need to know how to write the data structure without using its library? I know what stack is and how it works. I know how to make a Stack. But I am not sure if I can make a stack without using stack library file. So Do I need to learn DS without using their libraries too?

[@aqeebhj5467]

yes, you need to learn DS for the gate and other compt exams :)

[@aqeebhj5467]

sir can make some videos like this for c++ OOPs concepts
thanks in advance:)

[@RasGun_Travels_Life_Journey]

greatly explained

[@tomfranky1744]

What's the name of the text editor you're using in this video, please?

[@kowsiganr1058]

Bro vera level🔥🔥🔥

[@Fresherjobs24x7]

we write q.push or s.push in queue

[@shubham.papnai]

Chaitanya Sandeep doesn't matters. q or s or any other variable is just a stack variable or a queue variable, u can choose any variable name.

[@ayushjindal4981]

what was the logic behind using the extra stack object?

[@HimanshJainYTube]

We just want to print the stack. We don't want to delete it. So we make a copy of it to print it.

[@raghavnandwani4890]

Why did you copy both stack and queue before poping and printing?

[@AarushAgarwal]

So that original values are retained and only the values in the temporary variable are popped

[@karanh]

why did we use a temporary variable for printing a stack?

[@mankaransingh2599]

To preserve our original stack.
pop operation removes element from the stack, so we dont need that to happen with our original stack

[@thinkanddo2352]

Thank you sir!

[@scorpionnafis5703]

thanks bro❤️
