Removing the 1st element then 1st and 2nd element from a list of lists : <p>My aim is to remove the 1st element of a list and then the first and second element of a list etc. So a list entered like this: <code>[[1,1],[1,2],[1,3],[2,1],[2,2],[2,3],[3,1],[3,2],[3,3]]</code> will return a list like this: <code>[[1,2],[1,3],[2,3]</code>
I have tried many things but none work well</p>
