直接来看代码,来体会递归~
事实上,这个代码是最最让我体会到递归之美的~
好美啊~好妙啊~
#include<iostream> #include<algorithm> #include<cstring> #include<cmath> #include<cctype> using namespace std; #define maxn 0x3f3f3f3f int coun=0; void hanoi(int n,char a,char b,char c){ //将n个碟子,以b为中转,由a挪到c if(n==1){ cout<<1<<':'<<a<<"->"<<c<<endl; coun++; return; } hanoi(n-1,a,c,b); coun++; cout<<n<<':'<<a<<"->"<<c<<endl; hanoi(n-1,b,a,c); return; } int main(){ // freopen("in.txt","r",stdin); int n;char a,b,c; scanf("%d %c %c %c",&n,&a,&b,&c); hanoi(n,a,b,c); // cout<<coun; return 0; }
