Da esta salida para la entrada de muestra:
(~(((5)X(4))O(3)))a(~(1))
((~(((5)X(4))O(3)))a(~(1)))X(((2)x(1))x(3))
Para exprimir su tamaño:
- No realiza ninguna comprobación de errores, manejo de errores o validación de entrada, suponiendo que la entrada siempre sea válida.
- Está limitado a 99 líneas de entrada.
- Su archivo de entrada debe llamarse solo
r
, sin ninguna extensión de archivo en el nombre.
- No hace ningún esfuerzo para detectar si los paréntesis son o no necesarios. Se supone que siempre son necesarios, y dado que esta suposición es falsa, hay muchos más paréntesis de los necesarios, pero dado que esto no hace que falle la especificación de todos modos, no hay problema.
- El orden de los parámetros para cada operador binario es en general impredecible, ya que depende de la velocidad a la que se propagan los valores y del orden de exploración de la celda. Pero como todos los operadores binarios son conmutativos, esto no debería ser un problema.
Estoy seguro de que debería ser posible reducirlo más, pero solo un poco.
El intérprete se implementa en forma de algún tipo de autómata celular. Escanea todos los valores de configuración del campo, repitiéndolo tantas veces como sea necesario hasta que no se detecten cambios.
