Ratings and reviews

This app looks good, but I am able to see solutions only in C++, please inform way to get in java.

This is an amazing app! I am satisfied as a casual learner because there is so much content to get a hold of. Such a great productivity app!

Please I don't understand how it works. When I click on the problem part and I am given a question I don't seem to find a place to solve it especially the ones involving to write codes. Any feedback will be appreciated
