This CodeForces Round, 50-th already, will be carried out by me, Max Ivanov (e-maxx).
I invite to this round all schoolchildren who have just returned from their training camp "LKSH.Winter" - not to give their brains an excess respite, and all students - to distract from all the troubles caused by such a fearful phenomenon as the Examinations :)
The contest is over, congratulations for the winner - RAVEman!
Problem editorials:
The problems in this round will be five stories from a life of one Hedgehog (don't be surprised - hedgehogs are my loved creatures :) ).
