i need help in c implementing binary search tree i have the h file for the binary se 4949236

I need help in C++ implementing binary search tree. I have the.h file for the binary search tree class.
I have 4 classictexts, and 2 different dictionaries.
Classic Texts: Alice In Wonderland.txt A Tale of Two Cities.txt Pride And Prejudice.txt War and Peace.txt
2 different dictionaries: Dictionary.txt Dictionary-brit.txt The data structures from the standard template library can notbe used.The main program should open the text file, read in thewords, remove the punctuation and change all the characters to belower case, and then insert them into your data structure. Theprovided dictionaries are all lower case without punctuation. Oncethe structures are built, the program should write an output filewith the following format: The title of the first classic textNumber of words not appearing in the first dictionary, followed bythe words Number of words not appearing in the second dictionary,followed by the words The total number of words in the text,followed by the unique words (Note: this will be the same as theSum of the frequencies, and the number of nodes in your binarysearch tree for the classic text) The number of words in therequested word range and the frequency of each of those words:
The title of the first classic text
Number of words not appearing in the first dictionary,followed by the words
Number of words not appearing in the second dictionary,followed by the words
The total number of words in the text, followed by theunique words (Note: this will be the same as the Sum of thefrequencies, and the number of nodes in your binary search tree forthe classic text) .
The number of words in the requested word range and thefrequency of each of those words.
Their frequencies in a specified lexical range (calledRangeQuery) for each text (for example, all the words between raftand reflex might be : rag, rage, rails, rearranged, andreels). Here is the pseudo code for the
RangeQuery: Algorithm RangeQuery(key1, key2, v): Input: Search keys, key1 and key2 and a node v of a binarysearch tree T Output: The elements stored in the subtree of T rooted at vwhose keys are in the range [key1,key2] if T.isExternal(v) then return 0 if key1
I have to make 4 text files, one for each of the classictexts.
Here is an example of an output for all the wordsbetween raft and reflex in the War And Peace Text: War And Peace 0 2 : Michaela, gumshoed 10,431 total words 2,010 unique words 8 rag : 1 rage : 3 rails : 4 rearranged : 2 reels : 1
Here is my Code: // bst.h #ifndef bst_h

#define bst_h #ifndef NULL

#define NULL 0x00

#endif #include class BSTNode {



std::string data;

int frequency;


BSTNode *left;

BSTNode *right;




BSTNode(std::string d) { data = d; frequency = 1; left = NULL;right = NULL; }

~BSTNode() {} friend class BSTree;

}; class BSTree {



BSTNode *root; void destroy(BSTNode*);


BSTNode* find(BSTNode*, std::string); void increment_frequency(BSTNode *ptr);


void insert(BSTNode**, std::string);


void print_list(BSTNode*, int*);


void print_range(std::string, std::string, BSTNode*);   






void insert(std::string);


void print_list(int n); void print_tree(int n);


void print_range(std::string, std::string); // output all thestrings in the tree lexically between the parameters

}; #endif ——————————————————————– // bst.cpp //#include “bst.h”

//#include //BSTree::BSTree()


// root = NULL;

//} destructor:

// call destroy on the root of the tree destroy(BSTNode* p)

// **recursively** destroy the tree pointed to by p (whattraversal?) find(BSTNode* node, std::string word)

// **recursively** search for word starting at node

// return a pointer to the target node -OR-

// the pointer where the target node should be increment_frequency(BSTNode* ptr)

// increment the frequency at the node ptr insert( BSTNode* *p, std::string word)

// if the pointer p is pointing to null then

// create a new node at p

// otherwise, _insert_ word to the left or right subtree

// (**recursively**) insert(std::string word)

// insert word to the root of the tree by first _finding_ the

// place to insert. If word is already in the tree,_increment_

// its frequency, otherwise _insert_ the word print_list( BSTNode* p, int *n)

// if p is not null,

// if we have more to print

// recursively print the left tree

// cout the data : frequency and decrement the count (n)

// print the right tree. (what traversal?) print_list(int n)

// call print_list on the root print_tree(int n)

// call print_list on the root print_range( std::string k1, std::string k2, BSTNode* p)

// use pseudocode Range Query print_range( std::string k1, std::string k2)

// call print_range on the root of this tree ————————————————————– #include






// add any other needed include files.. int main(int argc, const char * argv[]) {


// declare the data structures here

// BSTree myTree;

   // Here is the code I started ..

// std::ifstream infile(argv[1]);


// std::string line;

// std::string word;   

// while(std::getline(infile, line))

// {

// std::istringstream iss(line);

// while(iss >> word)

// {

// word.erase(std::remove_if (word.begin(), word.end(), ispunct),word.end());

// std::transform(word.begin(), word.end(), word.begin(),::tolower);



// at this point word contains a punctuation free lower caseword

// from the text (HINT: do something with it)



// }

// }


return 0;
