The Montgomery Blair HS Computer Team is excited to present the fifth edition of Montgomery Blair Informatics Tournament (mBIT), which will be held online from 1:00 PM — 4:00 PM EDT on Sunday, May 22 (05/22/22). Note that the contest is 3 hours long this year.

If you are interested in competing, please register at https://mbit-live.mbhs.edu/. All problems were written by the Montgomery Blair Computer Team, including spiralsim, czhang2718, DanTheMan., gabrielwu, j0shua, nachoz, and srzhang. Special thanks to balbit and Giantpizzahead for testing >.<

mBIT is split into two divisions: Standard and Advanced. Teams may choose which division to compete in.

Advanced division problems are roughly equivalent to USACO Silver to Platinum and Div 1 in difficulty.

mBIT allows teams of up to 4 competitors! Anybody may compete, regardless of their age or country. To qualify for "high school status," all members of your team must be current high school (or middle school) students.
