How much do you know about character set encoding Ascii,unicode and UTF-8? This article will give you a thorough understanding of character set encoding. This article describes the problems and transformations of Ascii,unicode and UTF-8 coding, as well as example analysis. Start reading the article.

We know that inside the computer, all information is ultimately a binary value. Each bits (b
What is the relationship between utf8 and unicode encoding? What is the difference? UTF8 = Unicode Transformation Format -- 8 bit
It is a Unicode transfer format. Converts a Unicode file to a BYTE Transfer Stream.

The difference between Unicode and UTF-8 encoding Unicode is a character set, while UTF-8 is one of Unicode, Unicode is always dubyte, while UTF-8 is variable, for Chinese characters,

I. coding principles and implementation
Unicode encoding is the basis for UTF-8 and gb series encoding (gb2312, gbk, and gb18030) Conversion. although we can also directly create a UTF-8-to-these encoding table, but few people will do this, because the variable encoding of UTF-8 is uncertain, so the general use of unico

1. What is Unicode?
Unicode comes from a very simple idea: to include all the characters in the world in a set, as long as the computer supports this character set, it can display all the characters and there will be no garbled characters.
It starts from
This article mainly introduces how the JavaScript language supports the Unicode Character Set. For more information, see what I will share with you next month, and the support of the JavaScript language. The following is the lecture for this sharing.

The support for wide characters is actually part of the ansi c standard, used to support multi-byte expression of a character.
The width character is not exactly the same as the Unicode character. Unicode is only a type of width character encoding.

Brief introduction
Today's applications are often designed for international use. These applications may need to handle strings in different languages. Unicode is a language-independent character representation standard.
Because the Java programming language already uses Unicode internally to represent characters, the development of internationalized applications is much easier. However, you cannot consid
multiple bytes. For example, the common encoding method for simplified Chinese is gb2312, which uses two bytes to represent a Chinese character. Therefore, it can theoretically represent a maximum of 256x256 = 65536 characters.
The issue of Chinese encoding needs to be discussed in a specific article. This note does not cover this issue. It is only pointed out that although multiple bytes are used to represent a symbol, the Chinese character encoding of the GB class has nothing to do with the

Figure 1 shows a number triangle. write a program that calculates the highest sum of numbers passed on a route that starts at the top and ends somewhere on the base. each step can go either diagonally
Title:Given a triangle, find the minimum path sum from top to bottom. Each step of the move to adjacent numbers on the row below.For example, given the following triangle[ 2], [3, 4], [6,5, 7], [4,1, 8,3]]the minimum path sum from top to bottom is11 (i.e.,2 + +5 + 1 = one). Note:Bonus Point If-able to does this using only O(n) extra space, where n is the total number of rows in the triangle.

Given numrows, generate the numrows of Pascal ' s triangle.
For example, given numrows = 5,
Return
[[1],[1,1],[1,2,1],[1,3,3,1],[1,4,6,4,1]]
This problem is relatively simple, Yang Hui's triangle, you can use this column of elements equal to its top two elements of the sum to ask.
Mathematical solid people will see, in fact, each column

Printing Pascal Triangle seems like a easy problem, however, it isn't that easy to print a good-looking Pascal triangle.
To print the Pascal triangle, for each line, the "spaces" to "left of" numbers, and then print digit numbers.
To calculate Pascal numbers, two assays can is used:one array to store numbers of above, and the other array to store NU Mbers of this
