flip take['\0'..]
flip take['\0'..]
Not sure if it is possible to do any better without imports.
Edit
My first solution didn't actually print the result, so allow 6 more chars for that:
print.flip take['\0'..]
print.flip take['\0'..]
Also, not shorter (25 chars with printing, 19 without), but an interesting alternate approach (it requires 'Data.List', though):
print.((inits['\0'..])!!)
print.((inits['\0'..])!!)
