practice problems

Question

Where can I find solutions to practice problems when I am stuck?

Answer 1

I did but not all problems are here.

Also, the old version used to unlock answers.
With the new update, im stuck on a question and cannot move on next.

Answer 2

You can search by the name of the problem Here (Q&A Discussions)

Answer 3

I think if you submit a wrong answer, a comment button will appear in the bottom left, there you will find other people comments (answers) .
