I just wasted my 1 year.... Apna College walo k baato may aa kar ... C++ may DSA kar raha tha and the quality they delivered was horrible. Ja k unka recursion,graph,hashing dekh k aana, ye CP wale itna ganda padhaya kuch samajh nhi aaya. I'm glad i got Kunal's video in early 2nd year. I hope I'll prosper. Thank You so much Kunal , You're doing a great job!

Thank you for the course Kunal

[@lakshyakumarsirohi1950]

I'm a bit confused in the chart that was shown at the beginning, like isn't HashSet a class that implements the Set interface (but HashSet marked yellow for some reason) and also I had read that for interface to interface we can't use the impliments keyword but in the chart it's depicted that, Tree Set (Interface) implements the Sorted Set interface?? Can anyone clear that, my understanding is wrong or is it a mistake?

[@shubhamagarwal1434]

Can the background be bright instead of black or grey as it's not that good to focus while viewing. Please make it bright. Grey background is not good for viewing codes.
