Let's march ahead, and create an unmatchable DSA course! ❤

Can someone please add timestamps, I will add them post-it.

inspiration recording at 3 am when he can create content with so much dedication then why can't we learn dsa with same dedication hats off to you man.💯💯

In 4 years of college, when teachers came to copy and paste from their 10year old notes I couldn't gain any interest in DSA and felt stupid and never touched the topic post exam. And everything instantly clicked when I watched this video. Honestly your course is giving me insane confidence already. Hope I can make a change within a year, though it's difficult after doing full-time job but I get my confidence back when i see you making this huge stuff after working same or more hours. Planning to stay consistent! Thanks a lot!

PS: We have the same chair 😁

Superb explanation, sat for around 4hrs to understand how merge sort is working and then I found this video. Understood clearly within 50mins. Very nice and deep explanation.

[deveshmanitripathi]

Striver teaching how to code is just like a story. It really seems so easy to understand 😊

[prathamesh_utube]

Thanks Striver, I 'understood' it perfectly! This channel has the potential to become huge with content like this.

[Pooja-wexs]

Before I use to feel merge sort very difficult but after watching this video, I understood it very clearly. Thank you Striver.
