- Use the same input seed data you used for Lab 4 (your BST homework) as seed input data into a hash table.
- Declare a hash table of size 29 elements.
- To hash your currency objects into the hash table, use the pseudorandom hash scheme - (m*w + n*f) % size - where size = 29, m = 2, n = 3, w = whole value, f = fractional value.
- For collision resolution, use quadratic probing in the same direction always. Remember to circle around to the start of the array if needed.
- Your main will first load the data file into the hash table and print the number of data items loaded, load factor and number of collisions.

- To submit, upload your code files and screenshot of the console only.
- For documentation, only name blocks and existing documentation in your Dollar class are needed.
