Learning mathematical proofs for beginners (Proof of correctness)by Robin Kumar

If its added to the Competitive Programming playlist, it will be much much better.

I would suggest HackerRank and Programming Tutorials, Coding Problems and Practice Questions

These two Online judges have a very good practice section. There are many others but these two are better for beginners as you get problems that are classified topic wise and can be filtered based on the level of difficulty.
