Day 1

Kicking off my DSA journey with Love Babbar

Completed Lecture 1 2 & 3

Hoping to turn this start into a routine 🤞

I'm just following the series and solving problems
Any suggestions!!!!

@KSehgal23093 If you are keenly interested in DSA,I would suggest following Striver (if you’re comfortable with his teaching style)
Talking about Love Babbar, I’m not the right person to answer, as I discontinued it
Just a suggestion if you have enough time (if you’re a 1–2 year stud) try CP
