Andriy and Olesya take turns (Andriy starts) in a 2×1 rectangle, drawing horizontal segments of length 2 or vertical segments of length 1, as shown in the figure below. https://i.ibb.co/qWqWxgh/Kyiv-MO-2021-Round-1-7-2.pngAfter each move, the value P is calculated - the total perimeter of all small rectangles that are formed (i.e., those inside which no other segment passes). The winner is the one after whose move P is divisible by 2021 for the first time. Who has a winning strategy?Proposed by Bogdan Rublov gamecombinatoricscuttinggeometryrectangle
