Data Structure and algorithm 5: recursive (Recursion)Data Structure and algorithm 5: recursive (Recursion)
Preface
In the book Joel, chief of the programmer's tribe, who talks about software, the chapter "the school only teaches java risks" mentions
Definition: a sequence of numbers H0, H1 ,..., HN ,... If an integer N0 exists, when nn0 is used, you can use an equal sign (greater than or less than) to associate HN with some of the preceding HN (0i
There are three basic problems in the
Recursion is one of the basic modes for describing a process in a program computing process. we must be very careful before discussing the recursion problem, because recursion contains two aspects: one is a recursive computing process, the first is
Strings are the most data structure involved in programming, and the need to manipulate strings is almost ubiquitous. For example, to determine whether a string is a legitimate email address, although it can be programmed to extract the substring

Implement wildcard pattern matching with support'?'And'*'.
'?' Matches any single character.'*' Matches any sequence of characters (including the empty sequence).The matching should cover
String pattern matching refers to locating a particular pattern string where it appears in a longer string.
A simple pattern matching algorithm
It is intuitive to write the following code to find out where the pattern string appears in
Pattern matching algorithm for strings
The locating operation of a substring is often called a pattern match of a string, where T is called a pattern string .
General positioning function for substring position (Brute force)That's what
This part of the Main introduction to algorithms involves recursive, heap sorting, and quick sorting.
Exercise 4.1-1Prove that $ T (n) = T (\ lceil n/2 \ rceil) + 1 $ is interpreted as $ O (\ lg n) $.
Q: I guess $ T (n) \ Leq C \ cdot \ lg (n-B) $
