Write a method called arrayIsDoubled that takes two non-empty Int arrays (IntArray) and returns true if they are the same length and if every element of the second array is equal to the element of the first array in the same position, doubled.

So given {1, 2, 4} and {2, 4, 8}, you would return true, but given {1, 2, 4} and {2, 4} or {1, 2, 4} and {2, 4, 8, 10} you would return false.

We suggest you approach this problem by looking for a counterexample. First, examine the lengths of the two arrays. If they are different, you can return immediately! Otherwise, loop through each element of the array looking for one that is incorrect. As soon as you find one, you can return. And, once the loop concludes, you can also draw a conclusion.
