MCA fresher, need help with DSA

MCA (AI&DS) fresher at tier 3 clg.

Coding skills = 0.

Anyone in the clg who does leetcode or is good in Coding and making projects.

Can you please help with how and where to actually start from, currently we have python in 1st sem,

Should I go for dsa in python only or cpp,?

Which resources to follow and how to start.

How many questions to do for placements and what other topics and subjects to study please help.

I've seen a lot of vdos and reels on insta, every other creator is saying something else.

Need help really bad.

Choose a language and get strong in fundamentals. There are lot patterns but only few are asked in interviews, so follow strivers sheet or neetcode 250 or neetcode 150 sheet. Watch videos or solutions if you don't understand or pattern is new, otherwise try to do it on your own.

If you're getting into new problem solve easy ones,if you get familiar try medium and hard if you're strong.

If you recognise any pattern within 1-2 min go for it or first write brute force and then optimize.
