Hey, fantastic work. I'm glad you took my feedback and re-uploaded without music. The next step would be running your audio through a de-esser (which makes your 's' and 'sh' sounds a little bit less harsh), and in future recordings using a pop filter of some kind which makes not just your 's' and 'sh' sounds, but also your 'p' and 't' sounds more pleasant.

You are nailing the content and animation side of things.

Spending a few hours learning about how to make the audio as nice for the listener as possible is the next step to improving your overall content game. 🙏

Very very useful! Im saving this! Subbed !

Great😊👏 I'm gonna learn these first💪

I don't know how algorithm brought me here but I am glad it happened

Hey you are doing Great work keep up the work it's better than many channels

[amolbais]

Thank you so for removing background music 🎶

[michaelharrington]

Do you think being able to solve problems of the level you mentioned for each of these patterns will be good enough to get a junior position? I start applying this coming week

I greatly appreciate this video. I definitely need a more strategic approach to learn DSA. Memorizing solutions just doesn't work for my old(er) brain anymore. Have you considered mentoring?

Hey, thanks for this video. Including blog is great. I'll read it for sure.

What kind of videos are you planning to upload in the future?

My request would be to upload medium and hard questions based on faang interviews.

Also have you ever worked for any FAANG company?

Do you have group or channel on discord and whatsapp? That would be great too to get instant feedback and notifications for users.

Keep up the hard work👍🏻
