Aflu sa zicem doua A-uri, dau spamez AxAy ca unic determina x si y, candva ma opresc
Sa zicem ca am a A-uri si b B-uri
While (mai am nedescoperite)

Bag x1Ax2A...xkA, astfel aflu cate din x sunt A-uri dar aflu si exact cum e x1, il bag in A-uri sau B-uri si dau a++ sau b++
}
Fara ultima optimizare era fix 2sqrt, asa idk, doamne ajuta
