Print Dendrogram In Ruby
After waddling through a lot of Java code during the week, I decided to unwind in the weekend with Ruby code. And a favourite pastime is to convert Python code to Ruby code. I took one program, Dendrogram drawing -- a Python recipe, from the site code.activestate.com . What the program does is, to "Print dendrogram of a binary tree. Each tree node is represented by a length-2 tuple." When I read it first time, I too didn't understand fully as to what it does. In order to spare some of you the same agony, let's break down the quoted objective into key terms and get their meanings.
