What is copiedNums' length after the code segment? int[] originalNums int[] copiedums = {0, 0, 0); copiedNums = copy (originalNums, 2); = {1, 2, 3, 4); public static int[] copy(int[] nums, int changeAmt) { int[] modifiedums = new int[nums.length* changeAmt]; int index; for (index = 0; index < nums.length; ++index) { modifiedNums[index] = nums [index]; return modifiedNums;
