Question

The next structure you will investigate is the Hash table and its methods implemented in pseudo code when linked lists are used to handle collisions.;The task this week is to complete the pseudo code for the following hash table operations;1.Insert;2.Remove;Assume Hashtable is a simple array of size 8, with indices 0..7. Numeric keys are mapped by a Hashfunction that gives the mod(8,n) value for any key ?n? yielding the Hashtable index for that key (0..7). A Hashtable entry is null unless a key exists with that index as its hashed index, if so, the Hashtable entry points to the first node of a linked list of keys with that hash index. The last node on this linked list has a null reference for the next referenced node. Assume the occurrence of a linked list node is represented by the object ?Node? and its ?Data? and ?NextRef? attributes.;Week 2 Deliverables;?1 pseudo code implementation of each Hash table operation: Insert and Remove;?Fully documented pseudo code.;?Add the completed pseudo code and the output to the Key Assignment template Section 2: Hashing, Heaps and Trees.;?Name the document "IT265__IP2.doc.
