例3-10(书上）//3_10.cpp#include using namespace std;//把src针的最上面一个盘子移动到dest针上void move(char src, char dest) { cout << src << " --> " << dest << endl;}//把n个盘子从src针移动到dest针，以medium针作为中介void hanoi(int n, char src, char medium, char dest) { if (n == 1)move(src, dest); else {hanoi(n - 1, src, dest, medium);move(src, dest);hanoi(n - 1, medium, src, dest); }}int main() { int m; cout << "Enter the number of diskes: "; cin >> m; cout << "the steps to moving " << m << " diskes:" << endl; hanoi(m,'A','B','C'); return 0;}试问：（1）当盘子的个数 为5时，hanoi函数被调用了（ ）次？（2）当盘子的个数 为10时，hanoi函数被调用了（ ）次？
