Começando agora "Duvida com algoritmo"

[RodrigoPietro]

Começei pegando uma pedreira, pelo menos para mim, não sei se para algue ai é molezinha.. hehehe

Tenho que fazer um algoritmo (pode ser em qualquer linguagem) que:

possuo o arquivo cycle, nele tenho uma estrutura e preciso fazer o seguinte..

1 encontrar qual numero tem no source e não tem no Target (este é meu ponto inicial)

2 encontrado esse numero ele é o primeiro do fluxo.

3 localizando o numero (140866 primeiro do fluxo) seu target é o proximo do fluxo (116852)

4 então deve localizar o proximo source correspondente para achar o proximo target que será o terceiro do fluxo

ex: |140866| - |116852| - |117330| e assim vai até o ultimo numero

alguém poderia ajudar?
