Wtf is the task?

"Take the example: 2-1-3-4..." The Author should have used this example instead of 1234 example. Thanks for the explanation, wanted to skip this one because i did not understand the challange, but now i will try it.

There is nothing wrong with that code, except you're printing l before assigning it the first word's length to it, so it obviously will print the initial value you set, that's 0. Not a kata issue.
