When you finish solving a problem, do you stop to think about your solution before moving on to something else? Do you talk to someone else to see if they solved it the same way? These are good habits to help you become a more resilient problem solver, and we hope the problems in this feature will give you lots of opportunities to explore your own and other people's solutions!
