假设有A,B,C,D四个,在A上有n个。要移动到D上
在4塔的情况下 先移动i个到B上,在移动剩下的n - i个到D上(此时是在3塔的情况下)
#include <bits/stdc++.h> #define int long long using namespace std; int f[15],d[15]; signed main(){ // freopen("in","r",stdin); ios::sync_with_stdio(0); d[1] = 1; for(int i = 2; i <= 12; i++) d[i] = 1 + d[i - 1] * 2; memset(f,0x3f, sizeof(f)); f[1] = 1; for(int i = 1; i <= 12; i++){ for(int j = 0; j < i; j++) f[i] = min(f[i],f[j] * 2 + d[i - j]); } for(int i = 1; i <= 12; i++) cout << f[i] << endl; return 0; }
