Video Summary

In a game where Ranya and Wanya alternately placed tokens to create two piles, the goal was to determine which configuration was impossible. Ranya, with white tokens, started, and Wanya, with grey tokens, placed the last token. For every possible configuration, the topmost token must be grey, indicating Wanya's last move. However, in configuration E, the top token isn't grey, making it impossible according to the game's rules. Therefore, the configuration they could not create is E.
