今天学了一下.net的WCF组件,边心血来潮,想着现在不都是前后分离,调接口开发不,于是赶紧写了一简单的后台数据,哈哈 废话不多说,直接上代码: 注意需要导入库! 实体类:Customer using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace domain { public class Cust
题目分析: 首先跑个暴力,求一下有多少种状态,发现只有18xxxx种,然后每个状态有10的转移,所以复杂度大约是200w,然后利用进制转换的技巧求一下每个状态的十进制码就行了. 代码: #include<bits/stdc++.h> using namespace std; int n,m; ][],B[][]; ][]; // after number ],arr[]; ]; int calc(){ ; ;i<=n;i++){ans += kk[i][sit[i]-];} ; } in
