clojure find last element without using last function

Question

I'm learning clojure and have been using 4clojure.com to get better. I just completed #19 but it seems like maybe I haven't done it quite as the author's have anticipated - like I've perhaps missed the point somehow.

Given the constraint that you cannot use the last function does this seem like a reasonable solution?

#(.get %(- (count %) 1)) 

Answer 1

If you're going to use:

#(first (reverse %)) 

You might as well compose the function with "comp":

(comp first reverse) 

This is probably a little more idiomatic and easier to read. The same caveat about "reverse" not being lazy applies here.
