1. Consider the following mystery function on a binary tree (not necessarily a BST). public int mysteryHelper(TreeNode cur){ if(cur==null) return 0; else{ int r=mysteryHelper(cur. getLeft()) + mysteryHelper(cur. getRight()); if(((cur. getLeft()!=null && ((Integer) cur. getLeft().getValue())pareTo(cur. getValue())>0)|| (cur. getRight()!=null && ((Integer) cur. getRight().getValue())pareTo(cur. getValue())<0)){ r++; } return r; } } public int mystery(){ return mysteryHelper(root); }

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.
