Furnici
Lumea este în pericol. Încălzirea globală are efecte profunde în cele mai diferite domenii. Ea determină apariția extremelor climatice, topirea ghețarilor, ridicarea nivelului mărilor și, cel mai grav, dispariția a numeroase specii de animale. Cercetătorii au observat că cele mai afectate sunt furnicile.
Pentru a stabili cât de rapid este procesul de dispariție, ei și-au propus să le studieze timp de n
zile, notând în fiecare zi numărul de furnici lucrătoare care ies după hrană. Ei au constatat că ele sunt afectate dacă, în zile consecutive, numărul de divizori ai numărului de furnici lucrătoare descrește. Vor lua în considerare doar perioadele de cel puțin două zile consecutive de descreșteri.
Pentru finalizarea studiului, trebuie să știe câte astfel de perioade au existat. Pentru că la calculele matematice pot greși, vă roagă să-i ajutați.
