I try to find the boolean list for the first number in an strictly
increasing integer list. eg.
1, ( >:@}: ~: }.) 4 5 6 7 8 11 12 16 17 19 21
1 0 0 0 0 1 0 1 0 1 1
but it does not handle the corner case where the list is empty
1, ( >:@}: ~: }.) 0$0
1
I want it to return an empty list instead. Any idea?
