Maps the specified key to the specified value in this hashtable. Since the elements in the hashtable are indexed using the keys, the value of the key can be changed by simply inserting the updated value for the key for which we wish to change. Just as in the case of ht_insert, it should either free memory and exit if the program runs out of memory, or it should take a pointer to a heap allocated hash table (type HashTable_t **oht).
