Write a function called normalizegrades that receives a row array of test scores of arbitrary length and positive values, and produces two outputs: a row array array containing the grades normalized to a linear scale from 0 to 100 (i. e. grades are normalized if the maximum grade equals 100). hint: use the internal function max. the average of the normalized grades. hint: use the internal function mean. restriction: loops may not be used. for example, following code:

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.
