Which option is better? Option 1:
double d1 = 0.1; double d2 = 0.2; double d3 = 0.3; double x = (d1 + d2) + d3 ; double y = d1 + (d2 + d3); if (x == y) {System. out. println("Equal");}

Option 2:
double d1 = 0.1; double d2 = 0.2; double d3 = 0.3; double x = (d1 + d2) + d3 ; double y = d1 + (d2 + d3); double z = x - y; double epsilon = 1E-5; if (java. lnag. Math. abs(z) < epsilon) {System. out. println("Equal");}

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.
