Hanoi 问题
不解释！
#include <iostream> using namespace std; void Hanoi(int n, char src, char mid, char dest) { if(n == 1) { cout << src << " -> " << dest<<endl; return; } Hanoi(n-1, src, dest, mid); cout << src << " -> " << dest << endl; Hanoi(n-1, mid, src, dest); return; } int main() { int n; cin >> n; Hanoi(n, 'A', 'B', 'C'); return 0; }
