Use partition:

Or something like that. Not at a REPL so that's from memory.
Experiment with partition at the repl and it'll become clear.

My function accepts 2 parameters (a,b) and returns a result (c):

As a first approximation, literate programming needs to make it easy
to enter English text with code snippets that run. Haskell does this
by assuming that in a file ending in .
Clojure 1.2 has a shuffle function. If you're using 1.1, you can just
cop the 1.2 implementation.
