QuestionConsider the following definition of a MysteryBox object:public class MysteryBox {private final int x0, x1, x2, x3;private final double y0;private final boolean z0;private final long[] a = new long [248];}Using the 64-bit memory cost model from lecture, how many bytes does each objectof type MysteryBox consume? Include all memory referenced by the object (deep memory).AnswerYour answer should be a positive integer that is a multiple of 8. QuestionWhich of the following parent [] array(s) could be the result of runningthe weighted quick-union algorithm on a set of 10 items?Recall that our weighted quick-union algorithm uses union by size (number of nodes),not union by height.AnswerMark all that apply.O0 22 3 4 5 6 7 3 25855512 4 2 50011911161U42211 6 2 4 8 700397000 9 0
