Zen - C ++
Este Codémon no está aquí para comer sino para luchar. Él sabe que un enemigo muerto no robará sus manzanas.

Estrategia
Todos (excepto CircleOfLife) corren hacia las manzanas, pero no Zen, no siempre. Si el enemigo puede alcanzar la comida antes que él, simplemente espera en el centro (¿qué? ¿Pero qué haces aquí, CircleOfLife?). De lo contrario, Zen va a la manzana y se da vuelta mientras espera que algo suceda. De hecho, usa la manzana como cebo.
No codifiqué nada en contra de la curiosa estrategia de CircleOfLife porque solo puede ganar con mucha suerte.
