#2617

Gigel are o bucată de hârtie cu dimensiunile N*M și vrea să o taie în bucăți cu dimensiunile 1*1, respectând regulile:

• poate să taie o singură foaie la un moment dat. Nu poate suprapune mai multe foi și să le taie în același timp;
• fiecare tăietură se face dintr-o parte în alta a foii, pe verticală sau orizontală.

Scrieți un program care să citească numerele N și M și să determine numărul de tăieturi care trebuie efectuate.
