at first stage of us we don't even know how to think algorithmically thus we must load some best algorithms into our brain so brain get tuned later u solve it before 60 mins . yes ego won't make us do that and even understand my words. just like deep learning first feed then our brain understands better.

Yes it is needed. Most algorithms require a special type of DS (Data Structure) to solve

You should start learning a topic, solve its respective problems on LeetCode, then move on to the next topic, and attempt its questions, and so on

DSA isn't based on a language. Get familiar with learning the fundamentals like stacks, queue, list, set etc.

u can't do that learn DSA implement in language u like.😊

Basically how efficient collection logic is. Like if it always takes 1 loop, it's O1. If the collection has 10 items, and it takes 10 loops, it's ON

When someone reaches unbearable ecstatic climax that last more than 10 sec. Their mouth involuntary make an O shape, hence big (O)rgasm.

It describes how fast a problem will be solved or how fast the algorithm is in the worst case. For example Big O can be linear (O of n), quadratic (O of n squared), log.(O log of n), where n can be the number of people you want to count in a room for instance.
