Nu stiu, era ceva de genul, eu te pun sa alegi o carte si dupa aia o pui iar acolo fara sa-mi spui cartea si fac cate 3 teancuri si te pun sa-mi spui in care e cartea, apoi de 3 ori pun teancul cu cartea aia la mijloc si ultima data numar pana la 11 cartile si a 11-a e cea alesa de tine? Daca e asa tocmai ti-am explicat cum se face, daca nu, uite cateva lucruri asemanatoare! dar mai intai nu-i asa ca chestiile astea-s tari?
