Question 9

Time: 00:00:00
Alok and Bhanu play the following min-max
game. Given the expression N = 19 + X * (Y Z),
where X, Y, and Z are variables representing single digits
(0 to 9), Alok would like to maximize N
while Bhanu would like to minimize it. Towards this end,
Alok chooses a single digit number and
Bhanu substitutes this for a variable of her choice (X, Y or Z).
Alok then chooses the next value and
Bhanu, the variable to substitute the value. Finally,
Alok proposes the value for the remaining
variable. Assuming both plays to their optimal strategies,
the value of N at the end of the game would be
