In index page, every topic is associated with a page number. If we want to look some topic, we can directly get the page number from the index. Likewise, in hashing every value will be associated with a key.

A hash table is an array of items, which are { key: value }pairs. First, define the item structure: Now, the hash table has an array of pointers that point to Ht_item, so it is a double-pointer. Your hash table will need to return the number of elements in the hash table using count and size of the hash table using size.
