Hi
gTst3 right left = if (lr > ll) then False else True where lr = length (right ! 2) ll = length (left ! 2)
Running this code over HLint (http://www.cs.york.ac.uk/~ndm/hlint) says: Example.hs:8:1: Error: Redundant if Found: if (lr > ll) then False else True Why not: not (lr > ll) Making that change and running it again gives: Example.hs:8:1: Error: Use <= Found: not (lr > ll) Why not: lr <= ll Which ends up with something similar to what you came up with. However, if we take your final answer:
gTst3 right left = (lr <= ll) where lr = length (right ! 2) ll = length (left ! 2)
We get: Example.hs:8:1: Warning: Redundant brackets Found: (lr <= ll) Why not: lr <= ll Leaving us with the HLint 1.0 compliant (TM) : gTst3 right left = lr <= ll where lr = length (right ! 2) ll = length (left ! 2) Thanks Neil
