Anybody knows how can we suggest to SoloLearn include the improve for, that is, the for-each feature?

Question

for (int x : nums) { }, where num is an array.

Answer 1

You mean a lesson about enhanced for loops?
You could create and submit that in the lesson factory. Currently the lesson factory is in beta state, but you can submit lessons already:
