## Description
2018-10-10 16:20:40 -04:00
< section id = "description" > Tarea: < p > Resuelve el problema de las < a href = "https://en.wikipedia.org/wiki/Towers_of_Hanoi" title = "wp: torres_de_hanoi" > Torres de Hanoi</ a > . </ p >< p > Su solución debe aceptar el número de discos como los primeros parámetros, y tres cadenas utilizadas para identificar cada una de las tres pilas de discos, por ejemplo < code > towerOfHanoi(4, & #39 ; A& #39 ; , & #39 ; B& #39 ; , & #39 ; C& #39 ; )</ code > . La función debe devolver una matriz de matrices que contiene la lista de movimientos, origen -> destino. Por ejemplo, la matriz < code > [[& #39 ; A& #39 ; , & #39 ; C& #39 ; ], [& #39 ; B& #39 ; , & #39 ; A& #39 ; ]]</ code > indica que el primer movimiento fue mover un disco de la pila A a C, y el segundo movimiento fue mover un disco disco de pila B a A. </ p ></ section >
