In this pdf there’s most of the Nahamcon2021 Challenge who were “basic” and pretty straight forward and for this reason a unique post for them is not required.
Don’t get me wrong, all of this challenge have some to offer and can be a starting point for understanding a new argument or simply make you think a bit and hopefully have fun as they’ve done with us!
This pdf contains challenge solved by both, @ivanv and @whitegrizzly, not in particular order.
