You will vary the size of the table and count the number of collisions that occurs with each table. Includes the following basic methods: init - mark all positions of the table as empty. hashMe - calculate the hash index based on properties of the data. getNextOpenPosition - in the event of a collision, search table for the next available piece of memory. showTable - prints out occupied positions in table. rehash - when collisions become frequent, allocate a new table with a larger size and then rehash the data from the current table into the new table using a hash function that is modified to take the new table's size into account.
