Data Struct repo

Something notice and convention:

• .h file contains function implementation for convenience
• assume all number which maybe use is int type (yes, it is totally a toy project 😂)
• use CLion 2020.2.3 compile
• compile standard is c99

Target:

In This repo, I consider a most simplify implement to common data struct and some algorithm method(like sort)

The following list is the struct of the repo:

(Some of these data structures have not yet been implemented)

LinkedList

• ListNode

  leetcode style linked list

  you can use it construct linked list to test your algorithm vaild or not

  define:

  typedef struct list_node {
      int val;
      struct list_node *next;
  } ListNode;

  function:

  createListNode
  createLinkedList
  visitLinkedList

  I recommand you use ListNode to quickly construct a linked list

• SingleLinkList

  A single linked list

  define:

  typedef struct node {
      int val;
      struct node *next;
  } Node;
  
  typedef struct linked_list {
      Node *head;
      int size;
  } *LinkedList;

  function:

  isEmptyLinkedList
  createEmptyLinkedList
  addLinkedListNodeNum
  reduceLinkedListNodeNum
  insertNodeHeadToLinkedList
  insertNodeTailToLinkedList
  createLinkedListFromArray
  popFrontNodeFromLinkedList
  popTailNodeFromLinkedList
  popNodeFromLinkedListAtPos
  insertNodeToLinkedListBeforePos
  sortLinkedList
  visitLinkedList
  linkedListTransformToArray

• SingleLinkedListWithTailPointer

  a single linked list with tail pointer

  define:

  typedef struct node {
      int val;
      struct node *next;
  } Node;
  
  typedef struct linked_list_with_tail_pointer {
      Node *head;
      int size;
      Node *tail;
  } *LinkedListWithTailPointer;

  function:

  isEmptyLinkedListWithTailPointer
  createEmptyLinkedListWithTailPointer
  addLinkedListWithTailPointerNodeNum
  resetLinkedListWithTailPointerPointer
  reduceLinkedListWithTailPointerNodeNum
  insertNodeHeadToLinkedListWithTailPointer
  insertNodeTailToLinkedListWithTailPointer
  createLinkedListWithTailPointerFromArray
  popFrontNodeFromLinkedListWithTailPointer
  popTailNodeFromLinkedListWithTailPointer
  popNodeFromLinkedListWithTailPointerAtPos
  insertNodeToLinkedListWithTailPointerBeforePos
  sortLinkedListWithTailPointer
  visitLinkedListWithTailPointer
  linkedListWithTailPointerTransformToArray

Tree

TODO

Stack

TODO

Heap

• MaxHeap

  define:

  typedef struct max_heap {
      int size;
      int *array;
  } max_heap, *MaxHeap;

  function:

  maxHeapify
  createMaxHeap
  createMaxHeap_deep
  popMaxHeapRoot

• MinHeap

  define:

  typedef struct min_heap {
      int size;
      int *array;
  } min_heap, *MinHeap;

  function:

  minHeapify
  createMinHeap
  createMinHeap_deep
  popMinHeapRoot

The following list is the method of the repo:

Sort

implement 10 sort method in this repo

void bubbleSort(int *A, int n);

void bucketSort(int *A, int n);

void countingSort(int *A, int n);

void doubleBubbleSort(int *A, int n);

void heapSort(int *A, int n);

void insertSort(int *A, int n);

void mergeSort_2(int *A, int n);

void quickSort(int *A, int n);

void radixSort(int *A, int n, int m);

void selectSort(int *A, int n);

void shellSort(int *A, int n);

---

Coding style:

• use CLion to format code indent
• use under score case to name variable
• use upper case to name const variable
• use lower camel case to name function
• use lower case and underline to name struct
• use Upper camel case to name variable defined by typedef
• function name with __ denote is private function(for expect)
• function name with _ will carry some addition information, like mergeSort_2 denote it is 2 road merge sort

I make a mind map to help you understand this repo struct
