help with creating a hash table
I'm writing a program that find solutions to the 8-puzzle game
I need to make a hash table that has 2 operations
member(node *) which takes a pointer to a node and determines if the board in the node is equal
// member method to see if a value is in the table
// I'm not sure how to adapy this code
int hashtable::HLookup(int value){
// get the index
int index = hash(value);
// get the location in the table
node *p = table[index];
// p is the head of a linked list, so now we need to
//scan the link list to find the value
int found = 0;
while(p != NULL)
{
countHash++;
// see if the current element matches
if(p->value == value)
{
found = true;
break;
}
// go to next element
else p = p->next;
}
return found;
}
insert (node *) which puts a new node in the hash table
// insert method
//not sure how to use a pointer here
void hashtable::HInsert (int value){
node *p = table [hash(value)];
if (p==NULL){
countHash++;
table [hash(value)] = new node;
table [hash (value)]->value = value;
}
else {
while (p->next !=NULL){
p = p->next;
countHash++;
}
p->next = new node;
}
}
