seeking a lazy way to interleave a constant

2012-04-09 Thread Andrew
Given a lazy sequence of numbers is there a way to interleave a constant and get another lazy sequence? Say the first sequence is 1 2 3 4 ... I'd like the second sequence to be 1 0 2 0 3 0 4 0 Thanks in advance! -- You received this message because you are subscribed to the Google Groups
