View Full Version : Array "subtraction"

I need the perl code to -- for lack of a better word -- "subtract" one array from another, ie,

@array1 = (1, 2, 3, 4)

@array2 = (1, 2, 3, 4, 5, 6, 7, 8)

After "subtracting" a1 from a2, we get:

@array3 = (5, 6, 7, 8)


I have a feeling this is easy, but I'm a novice so I'm asking for help. thanks in advance!
