    Dear Keerti, I just watched this video on LLD and UML, and I'm absolutely blown away! It was truly amazing! I must say your ability to simplify complex concepts and explain them with such clarity is impressive. Thanks to your captivating presentation style and visually appealing content, I was completely engaged from start to finish. Your enthusiasm is contagious, making the learning experience enjoyable and inspiring! Love you!

    Request :: Make a playlist of lld for a beginner from scratch. For a student who doesn't know anything about LLD so pls structure the playlist so that we can follow that one specific playlist bcz searching for LLD on KZread makes it very confusing cz there is no such specific dedicated playlist from scratch to interview ready

    Although nobody asked, but these tutorial videos on LLD are informative and helpful. You are putting so much effort into these videos, it is fine if you put paid promotions in the videos. You are already teaching for free and if someone doesn't want to see the ads then they can skip it.

    Thanks for the videos(not just this one all of your videos). Especially the examples that you gave were from real life and made sense. The video was clear and concise. I had just one about the hint that you gave which helps us decide between composition and aggregation, multiple instances of a class. So is it in simple terms if I have singleton class then it can't be a composition, did I get it right ?

    I have a doubt, the Customer can have Orders, we can say Customer Have Orders, the relationship is composite as Order cant exist without customer. So we can say Customer is like parent for order, but the order class can have customerId so now does that mean order has customer?

If so, why Car & Camera is Aggregation but Body & Eye is Composition ? 😵‍💫
