In scala how would you go about writing a list from a text file (sample shown below), the list should include just the items associated with the word which is the first element of each line..

sample textfile ERINA ER4 IY6 N GH0

PAKE PW EYD K

SUMP S AH1 D P

for example if I asked for PAKE

it should return List("PW", "EYD", "K")
