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
