[11:05]: The team UH_wake_me_up! is the first team that solves problem H .

[11:10]: If UH_wake_me_up! solves the problem problem A could take over the first position! It seems like they already woke up!

[12:06]: UH_wake_me_up! solved problems A and B and is currently leading! This was a risky strategy, since both problems can be solved with the same code, but the easy version is notably easier than the second, as the standing have shown so far.
