Write a code snippet to help Kelly with the following: Use the current ingredient composition given in comp to determine the initial ingredient composition. Store in the variable initial frac the initial fraction of the ingredient silver. Suppose Kelly decides to leave the soup cooking for a very long time, until the ingredient composition in the pot is no longer changing. Help her determine this final ingredient composition and store it in the vector final_comp, where each entry is the fraction in terms of mass of each ingredient, following the order in material list.

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.
