Lambda with receiver* A method in the body of a lambda function that can invoke a different object without any additional qualifiers, which is not found in Java.* Such lambda is called "Lambda with receiver"Let's start with a normal function as a counter-example:Fun Alphabet (): String { val result = StringBuilder () for (letter in ' A ' ... ') Z ') { result.append (letter) } result.append ("\nnow, I know the
in the example above, because Classnumber is a natural index, it doesn't need to be associated.However, most of the situations we encounter in our usual use are not like this, we may need to classify the characters according to character, and how to deal with such special cases.For characters, there is still a relatively simple way of processing in Java, where char is automatically converted to the corresponding number according to ASCII or Unicode code. It is also possible to use char directly
1, what is character encoding?
Character (Character) is the general name of words and symbols, including text, graphic symbols, mathematical symbols and so on. A set of abstract characters is the character set (Charset). Character sets appear to facilitate the dissemination and storage of information. Currently used in the character set are: Ascii,iso 8859-1,unicode,gb2312
2, what are the characteristics of various coding sets?
Ascii:
ASCII (American Standard Code for Information Interchange
A few days ago, when I made the online dictionary service on this site, I had a problem with the English alphabet fonts. In Baidu's English dictionary, the phonetic alphabet is made into an image. When the result is output, the corresponding phonetic alphabet image is output, but I don't want to use this method. I want users to directly see the phonetic
these occurrences, in order to obtain a ranking of the Competit Ors. These competitors often write very long texts with nonsense meaning; A sequence of 500,000 consecutive ' T ' s is not unusual. And they never use spaces. So we want to quickly find out what often a word, i.e., a given string, occurs in a text. More Formally:given the alphabet {' A ', ' B ', ' C ', ..., ' Z '} and both finite strings over That's

Problem Description:Special strings are often encoded in data encryption and data compression. The given Alphabet a consists of 26 lowercase English letters, which is a={a,b...z}. The long-order string produced by the alphabet is the order in which the letters appear from left to right in the specified string, in the same order as the letters appear in the alphabet

?More is Less-the 'math'
The alphabet has 26 characters. that's a lot more than 10 digits. if we also distinguish upper-and lowercase, and add digits to the bunch or the heck of it, we already have (26x2 + 10 )?62 options? We ca
whatever the other party (for example, with Morse code), the length of a few "0-1"? Uttered, is five bits. If you use the "Average information point of view" to study the process, you will find that some letters appear often, in addition Some are less often used, so the source of information is a bit characteristic, this characteristic is the information content is not "full". In layman's terms, it is assumed that only a part of the alphabet is used

All content from Baidu Encyclopedia1, HelveticaHelvetica is a widely used western writing body designed by Swiss font designer Edward Hoffman (Eduard Hoffmann) and Max Mieding (Max miedinger) in 1957. Helvetica was made by Mieding and Edward Hoffman in the Swiss Haas Foundry as a typographic-shaped metal. People were familiar with the "International Font Style" (also known as "Swiss Style"), such as Josef Muller-brockmann in 1896 to promote the Akzidenz Grotesk such sans serif fonts, Haas hopes
Algorithm Learning (5): algorithm Learning1. Caesar Shift Cipher (password)
Note: cryptography is one of the most interesting branches in programming. The algorithm used to study it generally started with a simple method named after the famous Roman Emperor Caesar. He used this method to convey his military secrets.
We will practice decrypting encrypted messages in this issue. The idea of this algorithm is very simple. Each letter in the original text is replaced by another letter.

is, how can you differentiate between Unicode and ASCII? How does the computer know that three bytes represents a symbol instead of three symbols? The second problem is that we already know that the English alphabet is only one byte to express enough, if Unicode uniform rules, each symbol with three or four bytes, then each letter must have two to three bytes is 0, which is a great waste for storage, the size of the text file will be two or three tim
