1. LSP introduction (LSP -- liskov substitution principle ):Definition: if every object O1 of type S has an object O2 of type T, replace O2 with O1 for any program P defined with type T, P is a subtype of T. The child type must be able to replace its base type. Also known as LSP Lee's replacement principle.The general understanding of this principle is that the methods of the parent class must be implemented or rewritten in the subclass. Ii. Example:F

replace the match with the match result of the regular expression with *functionregreplace (Reg, str) {varResult//Final output ResultsOut//The matching results returned by the regular exec each time it is run. Index//matches the position in the stringLength//Match Lengthresult= Str.split ("");//separate the strings to be matched into groups, waiting to be processed while(out = reg.exec (str)) {//Returns NULL if the match succeeds in returning an out array if there is no match or reaches the

This article mainly introduced the C # regular function usage, combined with the example form Analysis C # based on regular matching, substitution, extraction of related operations skills, the need for friends can refer to the following The examples in this article describe the use of C # regular functions. Share to everyone for your reference, as follows: The System.Text.RegularExpressions namespace contains classes that provide access to the. NET F

Recently done a functional module on the bank, the need to use the middle portion of the Privacy Information bank to replace, so write down, the following code: 　　The invocation and effect are as follows:Replacewithspecialchar ("Collian Stay", 1, 0, ' * ')-->result: Ke * stayReplacewithspecialchar ("622212345678485")-->result:6222*******8485Replacewithspecialchar ("622212345678485", 4, 4, ' * ')-->result:6222*******8485Note: If the incoming Startlen/endlen exceeds the string length, an su

the values of the grouped captures. Groups[0], storing the result of the entire regular match, Groups[1], storing the result of the first grouping match. So to take the result of grouping matches, starting from 1.The power of regular packet-matching replacements is beyond doubt, and it makes the program simple, but still satisfies our various needs. Any kind of powerful technology is like a sharp sword, with good use of more than half, with bad, endless. For example, I'm going to match the numb

A string substitution problem where PHP partially hides the variable * I give an example, say: $str = "13760721151"; I'm going to turn this phone number into: 1376****1151; It hides about one-third of what's in the middle. How to implement in PHP. Appreciate.... ------Solution-------------------- PHP Code ------Solution-------------------- PHP Code Built-in functions do not have $str = "13760721151"; 1376****11

1. Replace only the first occurrence of the string "Red bean";$s = "I am Carl Small Yew seedling Results"I ' am Carl small mung bean sprout 　　2. Replace all external strings without a tag "red bean";$s = ' i\ ' Carl Small Yew seedling Results"I ' am Carl small mung bean sprout 　　PS: If there are loopholes, look feel free.　　Regular expression substitution excludes specific cases

The advent of computers and programming itself is to liberate people from repetitive work and to do more meaningful things.In line with this principle, many of us can be said to be "lazy people".For example, right now, I have a need to change some of the strings in some of the files in some folders to other strings.As a veteran lazy man, be sure to know what weapons you have on hand to do this thing.Refine your requirements:1. The old string that needs to be replaced is mytable, and the new stri

Given a string, convert it to another string. The input to the program is two files. The first file holds some rules that convert the text of a second file. Each rule consists of two parts: A word that may appear in the input file and a phrase to replace it. The meaning of the expression is that whenever the first word appears in the input, we replace it with the corresponding phrase. The second input file contains the text that you want to convert.To put it simply, replace the corresponding wor

the input is the number of the cases. There is no more than cases.For each case, the first line contains a integer N, 1Next Q lines, each line contains three integers X, Y, 1OutputFor each case, print a number with a line representing the total value of the hook after the operations. Use the format in the example.Sample Input Sample OutputCase 1:the total value of the hook is 24. Changed the template, because only the output of the total interval of information, so can not query, direct

Php function overload substitution method. The alternative to php function overloading is not as common as OOP for weak-type languages. However, the weak types are not differentiated, so they cannot be implemented through these methods.
