Hints : (a) as a first step, i would recommend implementing your own ver- sion of hash sets, called "myhashset". i would suggest using the mylinkedlist class from the last assignment as an example. i. your hash set should support an "add" method, which takes in a string and puts it in the set. ii. your hash set should support a "contains" method, which takes in a string and returns true if it’s in the set, and false otherwise. iii. your hash set should contain an array for holding the underlying data. iv. your hash set should include a hash function. i suggest research- ing one on the internet and using that.
