Specify the situations that the Hash Function defined as Hash (key)=42 will create. If the key shows Polsson distribution in the Hashing Function, explain how we should create a Hash Function. For calculating Hash values of Strings in Java documentation; The function s[0] 31^(n-1) s(11 31^(n 2)+...+s(n-1) is proposed. Why is the value 31 chosen in this formula? Comment.
