Loop an Array and Assign Elements

In this challenge, you will start with an array of coordinates for a CNC machine containing x and y positions (in this case, we don't have z positions). You will need to parse this array and sort its elements into three columns: IDs, x coordinates and y coordinates. Elements are already ordered in triplets. In other words, the first, second and third elements are the ID, x coordinate, and y coordinate of the first data point; similarly, the fourth, fifth and sixth element are a triplet describing the ID, x coordinate and y coordinate of the second CNC datapoint and so forth until the end of the list.
