I'm currently learning the fascinating J programming language, but one thing I have not been able to figure out is how to filter a list.
Suppose I have the arbitrary list 3 2 2 7 7 2 9
and I want to remove the 2s but leave everything else unchanged, i.e., my result would be 3 7 7 9
. How on earth do I do this?
