Data structure practice problems on Hashing, thanks!

. What is the deletion cost for hashing with chaining? How did you derive it? Explain how quadratic probing and double hashing avoid primary clustering. . What is the running of unsuccessful search in hashing with chaining? How did you derive it? What is involved in rehashing? Which probing technique that is used with hashing with open addressing performs the worst? What properties must a hash function have to be good
