If the Scala implementation is incorrect, can the task please be clarified to avoid this misinterpretation. Alternatively, if all the other impementations are wrong, can the task please be clarified to avoid this misinterpretation :) --[[User:Jnd|Jnd]] ([[User talk:Jnd|talk]]) 10:20, 13 October 2014 (UTC)
:Hi Jnd. We have:
::''"Given M as a list of items and another list N of items chosen from M, create M' as a list with the first occurrences of items from N sorted to be in one of the set of indices of their original occurrence in M but in the order given by their order in N."''
:For:
:: <code>Data M: cat cat mat Order N: cat mat</code>
:The second cat in M is never indexed by an item in N. <br>
:There is only one cat in N which matches the first cat in M. mat matches the last item in M so only the first and last items in M ''could'' be rearranged by their order in N. --[[User:Paddy3118|Paddy3118]] ([[User talk:Paddy3118|talk]]) 11:08, 13 October 2014 (UTC)
