I am newbie at Haskell.

I am not able to write a program to find the number of unique elments in a
list in haskell.

I am also not able to write a porgram to find the elements in the
innermost list in a list within lists.

Can anybody guide me as to g\how to go about it or better still send me
the program.

It would be of great help.

Have a good day..
