Problem Description

There are $A$ cards with the number $0$ and $B$ cards with the number $1$ on a table. Also, the blackboard has a $0$ written on it.
An angel and a devil play a game as follows. The angel goes first, and each player takes the following actions in their turn:

• Angel: Selects one card from the table and adds its number to the number on the blackboard. Then, the selected card is removed.
