I have 2 lists of numbers:
List A - 5, 10, 15, 20
List B - 1, 2, 3, 6, 21
I want to filter list A such that it contains only the numbers where the number + 1 is in List B.
Using the example above, the filtered list would be 5, 20.
I don’t want to do this with looping, just straight filtering. Can’t seem to figure it out because the math operators aren’t available in the expressions where I need them to be. Anyone?
