An algorithm for automatically analyzing mobile phone numbers (such as AAAAABAB) is classified into aaaaa aaaa aaa aabbcc aabb aaabbb aabbb aaabababababab AAAAB ascending ABCD descending DCBA
I import a group of mobile phone numbers to the database through text (one line of mobile phone numbers). I need to write an algorithm to obtain the type of mobile phone numbers, such as mobile phone numbers (15836998812) this is AABB (because 9988 is AABB, as
How PHP compares two arrays for equality
There are two arrays of
$a = Array (' AAA ', ' BBB ', ' ddd ', ' aaa ');
$b = Array (' AAA ', ' ddd ', ' aaa ', ' BBB ');
How to compare whether these two arrays are equal, provided that you cannot sort using built-in functions such as sort ().
If you must use built-in functi

Range is a range, and the delete operation can be expressed in two ways: ① write a number directly to indicate the number of rows to be operated. sed '2d 'aaa.txt must be used to delete the second line in the aaa.txt file. The regular expression must be used to separate the two backslashes. sed '/^ Tom/d' aaa.txt # trim deletes the line starting with Tom in aaa.txt * if no range is spec
Matches a word boundary, that is, the position between a word and a space. It does not match any character.
Further text descriptions are still abstract.
Example 1: When expression "^ AAA" matches "xxx aaa xxx", the matching result is: failed. Because "^" requires matching with the start of the string, "^ AAA" can be matched only when "
The usage of Delphi tstringlist tstrings is an abstract class. In actual development, tstrings have the most applications besides the basic types.
We all know the general usage. Now we will discuss some of its advanced usage.
First, list the several attributes to be discussed:

2. delimiter delimitedtext
3. First read the names Values valuefromindex: commatext. How to use it? Use code to speak:

Further text descriptions are still abstract.

modifies the number of matches, you can repeat the match without repeating the expression.
Use the method: "Number decoration" is placed after the decorated expression. For example: [BCD][BCD] can be written as [bcd]{2}.
Example 1: Expression \d+/.? \d* matches the IT costs $12.5, the result of the match is: success; match to: 12.5; The match to is: start at 10, end at 14.
