[Haskell-beginners] Help in Haskell

[Andre Paulo Machado]

Hi folks..... Somebody could help me, please?

Please, I would like a help in haskell programming, because I have with
following question:

I need to create a list of strings, like as a graph.
See:

initiaList = [ ("BSB,"SSA"),
                   ("CNF","SSA"),
                   ("CNF","GIG"),
                   ("CNF","GRU"),
                   ("GIG","CNF"),
                   ("GIG","GRU"),
                   ("GRU","BSB"),
                   ("GRU","GIG"),
                   ("GRU","CNF"),
                   ("SSA","CNF") ]

With this list above, I will create a function that returns a path with max
number of links:
example:

maxLink = 4 (result until 4)

command:   myFunction "BSB"  "GRU" 4
result:          1st Option:   BSB -> SSA -> CNF -> GRU
                    2nd Option:  BSB -> SSA -> CNF -> GIG -> GRU
----------------------------------------------------------------------------
command:   myFunction "BSB"  "GRU" 3
result:          1st Option:   BSB -> SSA -> CNF -> GRU
----------------------------------------------------------------------------

How do this?
I'm waiting from you,
thank you so much.

Andre
