Hello everybody,  can somebody tell me as to what is wrong with the following code

myflatten::[(a,a)]->[a] myflatten [] = [] myflatten (fx,sx):xs = fx:sx:(myflatten xs)

It says that there is a parse error on the last line.. Thanks, Sunil.

Hi Sunil,

You need to wrap the pattern in parentheses, ie:

myflatten ((fx,sx):xs) = fx:sx:(myflatten xs)
