CF 1033822 - Пирожки
Vertices are binary strings $a{2t-1}ldots a1a0$ with exactly $t$ ones. A move consists of choosing $j in {1,ldots,2t-1}$ and swapping $a0 leftrightarrow aj$. Each move preserves the condition $sum{i=0}^{2t-1} ai = t$, hence maps $(t,t)$-combinations to $(t,t)$-combinations.
CF 1033824 - Марсоход
We are working with an interactive simulation on an $N times N$ grid that represents a Mars surface. Each cell in this grid is either safe or contains a hidden obstacle, and the goal is to reconstruct the entire obstacle map using a rover that can move and query its surroundings.
