递归_汉诺塔问题
public class Tower { static int nDisks=3;//盘子的个数 public static void main(String[] agrs) { doTwoers(nDisks, 'A', 'B', 'C'); } //topN表示从上往下数,第topN个盘子,需要从form移动到to上面,innner代表盘子上面的一组盘子需要缓和的地方 public static void doTwoers(int topN,char from,char inter,char to) { if(topN==1) System.out.println("Disk 1 from "+ from +" to "+to); else { doTwoers(topN-1, from, to, inter); System.out.println("Disk "+topN+" from "+from+" to "+to); doTwoers(topN-1, inter, from, to); } } }
