D - Yet Another Problem On a Subsequence CodeForces - 1000D The sequence of integers a1,a2,…,aka1,a2,…,ak is called a good array if a1=k−1a1=k−1 and a1>0a1>0. For example, the sequences [3,−1,44,0],[1,−99][3,−1,44,0],[1,−99] are good arrays, and the sequences [3,7,8],[2,5,4,1],[0][3,7,8],[2,5,4,1],[0] — are not. A sequence of integers is called good if it can be divided into a positive number of good arrays. Each good array should be a subsegment of sequence and each element of the sequence should belong to exactly one array. For example, the sequences [2,−3,0,1,4][2,−3,0,1,4], [1,2,3,−3,−9,4]

LNMP安装常见问题集锦（一） 1、ERROR: invalid PHP executable specified by TEST_PHP_EXECUTABLE = /usr/local/src/php-5.3.18/sapi/cli/php 出现情况： make php过程中的错误 错误意思： 关闭安全模式就好了，都是 safe模式的测试 惹的祸。最新版的php 安装 包中已经没有safe模块了。 解决办法： 该错误可以忽略直接make install 好了。 2、nginx: [emerg] getpwnam("www") failed 出现情况：刚装完nginx后，运行测试文件的时候。 错误意思：获得 www 用户失败。 解决办法：在nginx.conf中 把"#user nobody;"的前面#注释去掉，改为"user www www;" 3、nginx: [error] open() "/usr/local/nginx/logs/nginx.pid" failed (2: No such file or directory) 出现情况：刚 安装 完nginx后重启时报的错。 错误意思： 在 /usr/local/nginx/logs 目录下没有nginx.pid 解决办法： 运行这句话， 问题 解决 " /usr/local/nginx/sbin/nginx -c

https://codingvision.net/security/c-read-write-another-process-memory Today’s tutorial is about…processes’ memory! In this article I’ll show you how to read/write a process’ memory using C#. This is a good way to learn a part of WinAPI and also understand the basics of memory allocation. Before starting, we need a “target” - I choose notepad.exe . 1.Finding the Memory Address As you might probably know, applications store each variable’s value at a specific memory address , we need to know that memory adress in order to edit anything. Since there’s not other way around (or I’m not aware of it?

Another kind of Fibonacci Time Limit: 3000/1000 MS (Java/Others) Memory Limit: 65536/65536 K (Java/Others) Total Submission(s): 3509 Accepted Submission(s): 1401 Problem Description As we all known , the Fibonacci series : F(0) = 1, F(1) = 1, F(N) = F(N - 1) + F(N - 2) (N >= 2).Now we define another kind of Fibonacci : A(0) = 1 , A(1) = 1 , A(N) = X * A(N - 1) + Y * A(N - 2) (N >= 2).And we want to Calculate S(N) , S(N) = A(0) 2 +A(1) 2 +……+A(n) 2 Input There are several test cases. Each test case will contain three integers , N, X , Y . N : 2<= N <= 2 31 – 1 X : 2<= X <= 2 31 – 1 Y : 2<= Y <=

You are given an array a of size n , and q queries to it. There are queries of two types: 1 l i r i — perform a cyclic shift of the segment [ l i ,  r i ] to the right. That is, for every x such that l i  ≤  x  <  r i new value of a x  + 1 becomes equal to old value of a x , and new value of a l i becomes equal to old value of a r i ; 2 l i r i — reverse the segment [ l i ,  r i ]. There are m important indices in the array b 1 , b 2 , ..., b m . For each i such that 1 ≤  i  ≤  m you have to output the number that will have index b i in the array after all queries are performed. Input The
