I listed all the questions I was interested in based on my own situation. I wrote my own algorithms for other questions (not from the above two) for myself to learn and taste slowly. If you have any questions, please leave a message below your blog.

recursive methods to reverse a single-chain table:
Link reverselist (link * root, link P){Link T = NULL;If (p-> next! = NULL) // if it does not reach the end of the linked list, call it recursivelyT = reverselist (root, p-> next );Else // if it has reached the end of the linked list, change next of the first vertex of the linked list to null, and change the first node to the last node,{(* Root)-> next = NULL;* Root = P;}If (T! = NULL){T-> next = P;}Return P;}

. Any Type 0 language is recursive and enumerative. Conversely, recursive enumerated sets must be a type 0 language.
Type 0 grammar is a syntax with the least limit. The generative formula only needs to contain a non-terminator (uppercase) on the left, for example, a0 → A0, A1 → B.
Type 1 Grammar
Type 1 grammar is also known as contextual grammar. Based on Type 0 grammar, a new restriction is added: the right part of the generative formula has a length greater than or equal to the left part. The
You often encounter problems with string-wide permutations. For example: The input is {' A ', ' B ', ' C '}, and its full-array combination is abc,acb,bac,bca,cba,cab. For a string array of input length n, the total permutation is n!.Package Bayes;public class Recursiontree {public static void permutation (char[] s,int from,int to) {if (to{Return}if (from ==to){System.out.println (s);}Else{for (int i = from; I Swap (S, I, from);Permutation (S, from+1,

The result of a full arrangement of three characters for ABC is ABC,ACB,BAC,BCA,CAB,CBA. A realization idea can be described as follows: Step1, determines the first bit of the character, can be a, B or C. Step2, after the first character is determined, the remaining characters are perfection arranged.The C + + implementation is as follows:voidPermutation (Char* Chars,Char*begin) { if(*begin==' /') {coutEndl; return; } for(Char* p=begin;*p!=' /'
Full arrangement of strings
Enter a string that prints all the permutations of the characters in the string in dictionary order. For example, the input string ABC prints out all strings abc,acb,bac,bca,cab and CBA that can be arranged by the character A,b,c. The results are output in alphabetical order.
Adopt the idea of recursion:
The string that needs to be arranged is divided into two parts:
(1) The first character of the string;
(2) All characters
