reikia pagalbos su algoritmu

Niekaip nesugalvoju algoritmo :)

Reikia, kad pagal prekės kodą tai pačiai spalvai, pvz L-J301-DK.blue! nuimtų pasikartojančius img ir tiesiog surašytų img pozicijas 1,2,3. Po to kita spalva DK.green! jau paima sekančias tris foto, bet bet sekantiems dydžiams vėl surašo pagal skaičius, t.y. 4,5,6. Esmė - padaryti, kad nesidubliuotų nuotraukos ir kitiems dydžiams būtų nurodytos rodykles (nuotraukų pozicijos). Viską turiu javoje, galiu manipuliuoti duomenimis, tik nesugalvoju pačio algoritmo.

Tarkime, yra toks .txt:

Iki šiol pavyko pasiekti:

                           if(i == 1) {

                                       }  
                                   }

       }

Viskas gerai, išskyrus tai, jog absoliučiai visoms tos pačios prekėms variacijoms nurodomos tos pačios img pozicijos, kaip ir pirmajai variacijai, pvz - 1,2,3. Nors turėtų būti 4,5,6, paskui 7,8,9 ir t.t.
