Hi everyone, I'm very excited to announce JUST ACM HALF EXTREME!

This contest simulates IEEExtreme with the same rules.

It will be held in this group. Note the unusual start time. The contest will run for 12 hours, and there are no penalties for time or wrong answers, just like in IEEEXTREME.

The contest will begin with 5-7 problems, and every two hours, 2-4 additional problems will be released.

Each problem is worth between 50 and 250 points. Even if you cannot fully solve a problem, you can still earn points by partially solving it. For example, if the optimal solution for a problem is O(N) but your solution is O(N^2), you can still score some points. The more you optimize your code, the more points you can earn.

You can participate as a team of up to 3 members. Any team with more than 3 members will be disqualified.

Any attempt to cheat between teams, or using AI tools, will result in disqualification. Please enjoy the problems without cheating.

Finally, special thanks to the writers and the testers of the contest : Kilani,qaruti,OmarAli.,Rayano,sharaf_makahleh,TravisBickle,Yaseen_Ahmad,Saleh_Elnaji,M-Qawasmeh03,ayham_alsalman,JUST_Ace,hmsh,fettucci,mahmoud_zoubi,ZeroNeroIV
