Separate chaining
The simplest approach is called separate chaining. The idea is to think of each of the m locations of the hash
table as being simple head pointers to m linked list. The link list table[i] holds all keys that hash to location
i. To insert a key k we simply compute h(k) and insert the new element into this linked list (we should fi rst
search the list to make sure it is not a duplicate). To fi nd a key we just search this linked list. To delete a key
we delete it from this linked list. An example is where we use the last digit as the hash function (a bad choice
normally). Fig. C.23 shows separate ...
