## Coloring codeforces solution- A matrix of size n×mn×m, such that each cell of it contains either 00 or 11, is considered beautiful if the sum in every contiguous submatrix of size 2×22×2 is exactly 22, i. e. every “square” of size 2×22×2 contains exactly two 11’s and exactly two 00’s.

## The Strongest Build codeforces solution- Ivan is playing yet another roguelike computer game. He controls a single hero in the game. The hero has nn equipment slots. There is a list of cici items for the ii-th slot, the jj-th of them increases the hero strength by ai,jai,j. The items for each slot are pairwise distinct and are listed in the increasing order of their strength increase. So, ai,1

## Slay the Dragon codeforces solution- Recently, Petya learned about a new game “Slay the Dragon”. As the name suggests, the player will have to fight with dragons. To defeat a dragon, you have to kill it and defend your castle. To do this, the player has a squad of nn heroes, the strength of the ii-th hero is equal to aiai.
