市面上有介绍Delphi的书籍(近来Delphi的书也是越来越少了),但没有一本系统的介绍Lazarus的书,这本书是网上的仅有的一本Lazarus教程,目前全部是英文,不过我已经着手开始翻译,争取尽快翻译完供大家学习!(原书来自 freepascal.org ) code.sd28.Sept.2013 IntroductionThis book is written for programmers who want to learn the Object Pascal Language. It…
Chapter 1 Introduction 1.1 What Is Machine Learning? To solve a problem on a computer, we need an algorithm. An algorithm is a sequence of instructions that should be carried out to transform the input to output. For example, one can devise an algori…

BPF for storage:一种受外核启发的反式 译自:BPF for storage: an exokernel-inspired approach BPF主要用于报文处理,通过绕过网络栈提高报文的处理速度.本文则用于通过绕过存储栈(文件系统.BIO等层)来提高存储的读写效率,但在实现过程中也遇到了相应的挑战,如文件和块的映射关系,多进程共享存储块以及进程间的QoS等. 概要 内核存储路径开销占新式NVMe存储设备访问延迟的一半.本文中我们将探究使用BPF在内核的I/O处理栈中注入用户定自…
1306. Sorting Algorithm Constraints Time Limit: 1 secs, Memory Limit: 32 MB Description One of the fundamental problems of computer science is ordering a list of items. There're a plethora of solutions to this problem, known as sorting algorithms. So…
1352: New Sorting Algorithm Time Limit: 1 Sec Memory Limit: 128 MB Description We are trying to use a new sorting algorithm to sort a sequence with distinct integers. This algorithm will be end if the sequence is already in increasing order from…
Bubble sort,It's a relatively basic algorithm.The core implementation ideas are as follows: 1.Define an array,The length is N. 2.Compares each pair of adjacent items and swaps them if they are in the wrong order. such as: if (a[j - 1] > a[j]) {//The…

sorting 应该是最容易被考到的东西,自己老是学了背,背了忘.为了方便复习,这里进行总结 1. Bubble Sort 定义:每两个两个比较,每扫完一次,当前扫过的最大值放在了末尾. for i = (n-1) to 1 for j = 0 to i-1 if(A[j] > A[j+1]) swap Time Complexity: Best case : O(n) It can occur if the array is already sorted and no swap occurre…
Given a Weighted Directed Acyclic Graph and a source vertex in the graph, find the shortest paths from given source to all other vertices. For a general weighted graph, we can calculate single source shortest distances in O(VE) time using Bellman–For…
I collect and make up this pseudocode from the book: <<Introduction to the Design and Analysis of Algorithms_Second Edition>> _ Anany LevitinNote that throughout the paper, we assume that inputs to algorithms fall within their specified ranges…
DNA Sorting Time Limit: 1000MS Memory Limit: 10000K Total Submissions: 80832 Accepted: 32533 Description One measure of ``unsortedness'' in a sequence is the number of pairs of entries that are out of order with respect to each other. For instanc…
