Heaps, Trees and Hashing

Heaps, Trees and Hashing

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.”

Assignment only consists of 1 pseudo code, should not take more than an hour to complete work.
