<br>
At the moment I have a list of lists. The inner list is a coordinate, like (x,y) but is [x,y] instead. What I would like to do is group all the x&#39;s into one list, and the y&#39;s into another. I know I can do this with calling 2 maps on the container, but I would also like to do this in one iteration.<br>


<br>
Does anyone have any ideas?<br>
<br>
Thanks in advance,<br>
Bryce<br>
