CowboysAndAliens

#1163

Cei m cowboys și cei n aliens s-au întâlnit în vestul sălbatic și, păstrând tradiția locului, s-au așezat în șir indian. Cum cowboys erau gazde primitoare și în special foarte precaute, s-au gândit că între doi cowboys consecutivi ar fi bine să fie cel mult un alien (din motive de securitate). De asemenea primul și ultimul din șir să fie cawboys. Dilema care s-a ivit a fost numărul de moduri în care s-ar putea așeza în șir indian ținând cont de condițiile de securitate impuse.
