In our analysis of the select algorithm for a block size of 5, we compared the median of the medians with every other element in the input array to partition it. However, that led to more comparisons than we should have done. We could reduce it since we know that at least 3n/10 elements are less than or equal to the median of the medians and similar number of elements is at least greater than or equal to the median of the medians. Obtain a new upper bound on the worst-case number of comparisons using this piece of information. What is the value of the constant?

Write a method named addall that could be placed inside the hashintset class. this method accepts another hashintset as a parameter and adds all elements from that set into the current set, if they are not already present. for example, if a set s1 contains [1, 2, 3] and another set s2 contains [1, 7, 3, 9], the call of s1.addall(s2); would change s1 to store [1, 2, 3, 7, 9] in some order. you are allowed to call methods on your set and/or the other set. do not modify the set passed in. this method should run in o(n) time where n is the number of elements in the parameter set passed in.
