2,34. As the title says, the program is a personal behavior, in the case of ACM, such as the topic, according to the topic to write a number of lines of code, the use of an algorithm to complete the topic requirements, just input and output is enough, this can be said to be a simple program, is to complete a program. And a software is a large project, the software has a number of components, the need for a number of different people to work together, the design of the case-form interface, the es

IdeasUsing tree multiplication method can efficiently find two x, y common ancestor LCA.We set F[X][K] to represent the 2k generation ancestors of XF[x][0] is the parent node of XBecause 2k from the X-to-root node can be seen as 2k-1 step from X to 2k-1 step .So for 1≤k≤logn there is F[x][k]=f[f[x][k-1]][k-1] (similar to the dichotomy of thought)Pretreatment:So we can iterate over the tree and get all the f[x][0] and calculate all the values of the F-array.To seek LCA:Set Dep[x] to the depth of

performance, robustness, and scalability. The agent can not affect the performance of the monitored, function, or because the monitoring system to add new monitoring functions, and so that the old agent does not work properly.The monitoring log does not require direct intrusion into the code of the monitored person, but usually requires the monitored person to output the log according to certain rules. This is another form of code intrusion. In addition, log monitoring will have a certain delay

functions, approval functions, and task assignments in the company. Such frameworks are better known as business models than they are called business frameworks. It helps to understand the product and business logic, but also facilitates the maintenance of existing functionality and the expansion of new features.However, there is often a conflict between the strict business model and the system optimization. This one's been taken.From the perspective of improving the efficiency of development,

will not start from scratch. But the cost of the SP's staff may be questionable, but it should be a direction.3. New transactions are small and fastIn addition to the daily it and research and development work to adopt a "small and fast" principle, think it is worth a try to quickly build a small team quickly release results, and in the company training.4. Planning is importantMany of the company's it is not planning, or some only a year of planning, in fact it construction is a relatively long

When PHP parses a file, it looks for the start , the tag tells PHP to start and stop explaining the code in it. Parsing this way allows PHP to be embedded in a variety of documents that are ignored by the PHP parser in the case of anything other than a pair of start and end tags. In most cases, PHP is embedded in an HTML document. A single-line comment only comments to the end of the line or the current PHP code block, depending on which first appears. This means that in//...? > or # ...? The H

PHP programmers should know that connecting to a MySQL database can use the Mysql_pconnect (permalink) function, the use of a database permanent connection can improve efficiency, but the actual application of persistent database connection will often lead to some problems, The usual performance is the intermittent inability to connect to a database on a site with a large amount of traffic, and a similar "Too many connections in ...

relaxed layout, reducing the crosstalk between each otherTrick three is the amplitude modulation plus a high-frequency amplification, although only a simple amplification circuit, but the sensitivity is improvedThe trick is to use the reverse-paranoid capacitive effect of the common transistor-based polar collector, acting as a varactor diode to be used, and the circuit diagram is as follows:This frequency fine-tuning is very easy to adjust and smooth than tuning, compensating for some gear tra

It is difficult for me to understand the association class, and I think there are some problems here. Below are some articles or articles I have excerpted. The first is the basic definition of the associated class: An association class may have to record some information. You can introduce an association class to record it. Figure 3 introduces an association class based on Figure 2. The Association class connects to the association through a dotted line. Figure 4 is another way to achieve the ab

lot of unnecessary viewstates, in addition, the server control is translated into table, but not div + css. However, after the form is removed, many problems will emerge. For example, Page. ClientScript. RegisterStartupScript cannot be used! The ability to directly write js in the background is lost, because response. write will destroy the page structure, because it is independent of the page output. Therefore, it is very painful to define many global variables on the page, and then let the fr

1. You can use an object as a member field in Java. It is similar to the basic data type as a member field. When using this field, you must first instantiate the object, there are two methods: Class A {} Class B {A; B () {A = new A (); // first method} class c {A = new (); // type 2} 2. Access to object fields and Methods Access methods are divided into object fields and object methods, and each method is divided into static and non-state methods. 3. Use an object as a method parameter for t

Discussion: get/set accessors and actionscriptgetset for new JavaScript ECAMScript5 features Introduction to EcmaScript5 First, we must first understand that ECMAScript is a magic horse. We know that JavaScript or LiveScript was first developed by Netscape. Later, Microsoft also developed Jscript, and ScriptEase also had its own CENvi, in this way, three versions of browser scripts are used in different ways. Everyone understands this confusion, so th

memcached server cleanup policy is just a lazy cleanup. Let's take a look at the actual example: We have a version mark behind all the keys. "shop.200 _ 1" indicates the cache with the merchant ID 200 and version number 1. Once any merchant cache needs to be cleared, we only need to upgrade the version of shop cache. In the above example, the merchant cache versions have all been upgraded to 2, and the read key value has also changed. Therefore, the cache of the original shop. xxx_1
