Define the following terms: hash table hash function perfect hash function What is a collision? Explain three ways of handling collisions (a program is not needed; a clear brief explanation suffices). Consider a hashing scheme that uses linear probing to resolve collisions. Design an algorithm (no code necessary) to delete an item from the hash table. What precautions do you need to take to make it work properly? Given...

#3 [3 points] Sketch a hash table of size N=11, where the hash function is hash(key) = key mod N and quadratic probing is used to resolve collisions, after the following elements are inserted: 20, 42, 45, 49, 62, 72, 95. The probes are based on this equation: (H+c1∗i+c2∗i2)mod(N) and c1=1, c2=1. If direct hashing was used to store the same elements as the previous problems (20, 42, 45, 49, 62, 72, 95), what should be the minimum size of...

Suppose we wish to allocate a hash table, with collisions resolved by chaining, to hold roughly n=1000 character strings and we don’t mind examining an average of 3 elements in an unsuccessful search. If we choose the division method to design the hash function: 1) What is the load factor? 2) What value of 'm' should be picked? (m is the number of slots in the hash table) Explain briefly why you pick this m.
