You are given two positive integers aa and bb . In one move, you can change aa in the following way: Choose any positive odd integer xx (x>0x>0 ) and replace aa with a+xa+x ; choose any positive even integer yy (y>0y>0 ) and replace aa with a−…

A.Add Odd or Subtract Even 签到题~ #include<bits/stdc++.h> using namespace std; int T; int a,b; int main () { scanf("%d",&T); while (T--) { scanf("%d%d",&a,&b); if (a==b) { printf ("0\n");continue; } ==) { prin…

A. Add Odd or Subtract Even 思路: 相同直接为0,如果两数相差为偶数就为2,奇数就为1 #include<iostream> #include<algorithm> using namespace std; int main(){ int kk; scanf("%d",&kk); while(kk--){ int n,m; cin>>n>>m; if(n==m) {printf("0\n&qu…

题意: 定义 \[f(n)=\sum\limits_{i=1}^{n-1}(i\oplus (n-i))\] 求\(f(n),n \leq 10^{500}\) 分析: 这个数列对应OEIS的A006582 先上公式: \[f(n)=\left\{\begin{matrix} 4f(k)+6k,n=2k+1\\ 2f(k)+2f(k-1)+4k-4,n=2k \end{matrix}\right.\] 递推的思路就是虽然不知道两个数的异或值,但是如果知道这两个数的奇偶性那么结果的奇偶性也就知道了…

扯淡 13年毕业之际,进入第一家公司实习,接触了 EntityFramework,当时就觉得这东西太牛了,访问数据库都可以做得这么轻松.优雅!毕竟那时还年轻,没见过世面.工作之前为了拿个实习机会混个工作证明,匆匆忙忙学了两个月的 C#,就这样,稀里糊涂的做了程序员,从此走上了一条不归路.那会也只知道 SqlHelper,DataTable.ORM?太高大上,没听说过.虽然在第一家公司只呆了两个月,但让我认识了 EntityFramework,从此也走上了 ORM 的不归路...纯纯的实体,增改删…

1. Functional programming treats computation as the evaluation of mathematical and avoids state and mutable data. Scala encourages an expression-oriented programming(EOP) 1) In expression-oriented programming every statement is an expression. A state…
