Hi all,

I'm a complete beginner in DSA and I'm following Striver's A2Z DSA YT Playlist. The thing is that I'm confused about how to use the A2Z Sheet and the YouTube playlist both together.

For example, in Arrays, Striver has concept videos as well as problem-solving videos (3Sum, 4Sum, Reverse Pairs, Set Matrix Zeroes, etc.), and the same problems are there in the A2Z Sheet also.

Which approach is better?

Should I Watch all the videos first (including every problem-solving video), then solve the A2Z Sheet.
Or Watch only the basic/concept videos, then start solving the A2Z Sheet and watch the problem's video only if I get stuck.

Also, what about problems that introduce a completely new pattern (for example, Set Matrix Zeroes or other matrix problems)? Should I watch those videos first before attempting them, or should I still try solving them on my own?

Cos there are new patterns and concepts which i don't know at all, if i just start A-Z sheet wouldn't it be difficult to do without any concept building?

Ppl who did/doing striver A-Z Vid/sheet. kindly guide.

Need a CP/DSA partner.
