ACM impressions and learning logs of A New cainiao Feeling: I forgot when I liked ACM, maybe it was pitted, Or I liked it silently. I can't forget that when I first came to our school training base, I called Hong Ju xuejie (although she was not an ACMer). The first thing I saw was Zhou Hai, the captain of our training team. The code for the first successful knock is the accumulation of 1-50 as taught by Jun

Sometimes tools are too powerful, but getting started is difficult.Vim Command DaquanThis is the existence of VIM .In order to exercise the ability of the naked eye to debug and write the correct code, I decided to write code with a text editor.Because the main problem is to write ACM at this stage, it does not use special advanced features.1.

The first question of the ACM, Zhejiang University Calculate A + b InputThe input would consist of a series of pairs of integers a and b,separated by a space, one pair of integers per line. OutputFor all pair of input integers a and B should output the sum of a and B in one line,and with one line of output for E Ach line in input. Sample Input1 5 Sample Output6 HintUse + operator Toss a few times, miserable ah. Fortunately finally solved, otherwise

a referee program. The referee program either compares the output data of the user program with the standard output sample, or verifies that the output data of the user program satisfies certain logical conditions. The last system returns to the user a state: Through (ACCEPTED,AC), answer error (wrong Answer,wa), timeout (time Limit exceed,tle), exceeding the output limit (outputs Limit exceed,ole), Hyper-memory (Memory Limit exceed,mle), run-time error (Runtime error,re), malformed (presentati

The words in Windows core programming cannot dispel the doubts in the mind. Let the explanation on MSDN give us a lamp. If you want to introduce it in detail, or go to MSDN for a closer look, I'm simply describing it in an easy-to-understand language. Windows Security access Control (acm,access control mode) is made up of two parts. One is the access token (access tokens) and the other is the security descriptor (identifiers). An access token is infor

Problem DescriptionWowapps most like to learn English, English class never skip class, but English has not been learned, because the class has been sleeping. Why do you sleep, because he thinks the English word is too long. Now Wowapps has a long, long, long word and wants to compress it. Can you help him?Compression: Replaces consecutive repeating letters with one, see sample for details.InputEnter an n first to indicate the number of words Wowapps give (1Next n lines, each behavior of a string

Problem DescriptionTomorrow will be the English exam, Wowapps is Midnight Oil recite the words. Wowapps found the word difficult to recite, the back one forget. After careful study, Wowapps found that the reason why the word is difficult to recite is because of the appearance of a character, destroying the beauty of the whole word, resulting in poor memory. Wowapps decided to destroy these discordant characters on behalf of the Moon!! (Applause!!) But the exam has entered the countdown, and Wowa

Analysis: At the same time calculate the shortest distance and cost, the distance is also to update the cost, but also to store both forward and reverse edges.Note: You cannot use CIN and cout, otherwise you will time out.#include HDU ACM 3790 Shortest path problem (SPFA algorithm implementation)

Analysis: First, the number of strong connected components, then the contraction point, and finally find the final answer.1. Use Tarjan algorithm to find the number of strong connected components.2, the contraction point for another graph, through the Tarjan algorithm to find the results. The degree of each point is calculated in the graph after the indent.3, to find out the minimum cost of each strong connected component.4.
