%this one calculate the maximum of a list of tuplos
maxTuplo([],_,0).
maxTuplo([ [Nome,NumeroVoos]|Resto],Nome,NumeroVoos
):-
maxTuplo(Resto,_,MaxNumero),NumeroVoos >= MaxNumero.

maxTuplo([ [_,NumeroVoos]|Resto],Nome,MaxNumero):-
maxTuplo(Resto,Nome,MaxNumero),NumeroVoo
s < MaxNumero.

%maxTuplo([[porto, 7], [londres, 11], [madrid, 7], [paris, 7]],X,N).
X=londres
