Branch launches

Branch is a place to work through interview problems with friends.

• Create a group and invite friends with a link.
• Pick a roadmap (Patterns 150, Essentials 75, or your own) and a weekly pace.
• Everyone sees the same problems each week; mark them solved and see who's done what. Falling behind leaves a backlog, and you can always work ahead.
• A problem you solve counts once, in every group and roadmap it appears in.
