Create a program which reads in CSV data of Creatures and loads them into aHash Map. The key of this hash map will be the name of each creature. For your hash function, you can simply use the sum of all ASCII values. You can also come up with your own hash function. Your program should present a menu to the user allowing them to look up a creature by name. Additionally, create a function that allows the user to insert a new creature. This creature should be added to the existing hash map. If the name entered by the user already exists, DO NOT ADD IT TO THE HASH MAP. Simply report that the creature already exists. If the creature is unique and successfully added, report the calculated index value. Your hash array should start as size4. You will need to implement a rehashing function to maintain a load factor of 0.75. Collision resolution should be handled via separate chaining with linked lists. Other Requirements
•Read in a CSV file from the command line when running the program.
•Convert the raw CSV data into the creature struct and add it to a HashMap
•Make sure you properly release all of your allocated memory.
•Format your code consistently.
•Function declarations, structs, and preprocess directives should be placed in a corresponding header file.
•Save your code for this problem ascreature_hash.(c|h).
Creature struct
typedef struct {
char name;
char type;
int hp;
int ac;
int speed;
} Creature;

Explanation:

class TableInput{

Object key;

Object value;

TableInput(Object key, Object value){

this.key = key;

this.value = value;

}

abstract class HashTable {

protected TableInput[] tableInput;

protected int size;

HashTable (int size) {

this.size = size;

tableInput = new TableInput[size];

for (int i = 0; i <= size - 1; i++){

tableInput[i] = null;

}

abstract int hash(Object key);

public abstract void insert(Object key, Object value);

public abstract Object retrieve(Object key);

}

class ChainedTableInput extends TableInput {

ChainedTableInput(Object key, Object value){

super(key, value);

this.next = null;

}

ChainedTableInput next;

}

class ChainedHashTable extends HashTable {

ChainedHashTable(int size) {

super(size);

// TODO Auto-generated constructor stub

}

public int hash(Object key){

return key.hashCode() % size;

}

public Object retrieve(Object key){

ChainedTableInput p;

p = (ChainedTableInput) tableInput[hash(key)];

while(p != null && !p.key.equals(key)){

p = p.next;

}

if (p != null){

return p.value;

}

else {

return null;

}

public void insert(Object key, Object value){

ChainedTableInput entry = new ChainedTableInput(key, value);

int k = hash(key);

ChainedTableInput p = (ChainedTableInput) tableInput[k];

if (p == null){

tableInput[k] = entry;

return;

}

while(!p.key.equals(key) && p.next != null){

p = p.next;

}

if (!p.key.equals(key)){

p.next = entry;

}

public double distance(Object key1, Object key2){

final int R = 6373;

Double lat1 = Double.parseDouble(Object);
