The Matryoshka Doll Surprise questions. A Matryoshka consists of n dolls, each consists of the lower part called the base and the upper part called the top. You are given a box n bases and n tops. They are given separate from each other, and in an arbitrary order. No two bases have the same size, and no two tops have the same size. The problem is to determine if each base has a matching top. The only reason that a base might not match a top is if they have di erent

(java)3. the answer is  (c): x[2] = 12; if x is an array with three elements, the first element has index 0. the second index has index 1. the third and final element has index 2.4. the answer is (d) for (int y : x) { system.out.println (y) ; }this is an example of syntax  of a "for-each loop."for each element in the integer array x, use y to indicate the current element to do some code with it.the other choice, (c) for (int x : y) { system.out.println (y) ; }. in a for-each loop, the variable to the right of the colon is the array variable; the one to the left is the control variable.choices (a) and (b) have invalid syntax.5. the answer is (a)  int x = {1, 2, 3, 5, 10}; you need to indicate that it is an array using []. without using [], you are trying to assign an array to an integer. you need to use int[] to indicate integer array.so choice (a) has incorrect syntax.
