For one step, there's one way (s(1) = 1). For two steps, two ways (s(2) = 2). From the third step, you can choose to go to step 1 or 2. The number of ways is s(1) + s(2). For four steps, you can go to step 3 or 2 (s(3) + s(2) ways). It's Fibonacci again.Scotthttp://www.blogger.com/profile/05511964464437000519noreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-3571805442702052082014-08-11T21:17:33.204-07:002014-08-11T21:17:33.204-07:00@Ramesh Kumar
