Hello, Codeforces Community!

I invite you all to join HackerRank's University CodeSprint 3 starting on 29th September 2017. The contest duration is 48 hours.

The winners of the contest will win up to 1000USD cash prizes. The top 100 will also win awesome hoodies. (Winners will be required to give proof that they are currently enrolled in the university they represented during the University CodeSprint.)

The contest will be rated. If two people get the same score, the person who reached the score first will be ranked higher. There will be a separate rank list for schools.

There will be 7 algorithmic challenges in this contest. Some of them will have subtasks, so I highly recommend you to read all of them.

The problems were created by immuntasir, sreka11, svanidz1, sgtlaugh and Hillan and tested by Shafaet, pkacprzak, wanbo, Wild_Hamster and me. Big thanks to Wild_Hamster for helping to review and test most of the problems.

Good luck and happy coding!
