Your projects / imagination / projects on the advice of senior colleagues VS Codewars / Hackerrank / Leetcode?

Question

IT education

Hello!

Please tell us your reasoned opinion on how best to practice learning programming!

I started learning java and after going to multithreading, I went to codewars/hackerrank/leetcode

And I'm trying to understand the following:
1. Is it worth solving all tasks from 8 to 1 Kyu
2. Maybe it's worth taking some real programs/projects and looking for ways to create them, read books on algorithms in parallel and try to implement them?

Please advise if it is worth visiting the site:
1. Codeforse
2. Codewars
3. HackerRank
4. LeedCode

how to stop in time if the sites are still good, I thought after getting to know the language to open a book on algorithms and write programs using them, SO SAY IN BATTLE!???

Answer 1

Github.com
What's the point of programming if it doesn't solve applied problems?

Answer 2

1. You need real projects to understand that you don’t know anything yet, but this will be a great opportunity to learn.
2. You need to run puzzles from time to time in order to tune your brain to solve through algorithms, and to look at the solutions of others, thereby learning various language tricks, unknown built-in functions and, of course, someone else's train of thought.
If you only solve problems, you will become a great problem solver, but you will not advance one iota as a specialist useful for a company with real products.

Answer 3

1. yes
2. yes
and everything else yes
no or or, everything needs to be done
