3. Alice and Bob play the following coins-on-a-stack game. 100 coins
are stacked one above the other. One of them is a special (gold) coin and the
rest are ordinary coins. The goal is to bring the gold coin to the top of the
repeatedly moving the topmost coin to another position in the stack. Alice
starts and the players take turns. A turn consists of moving the coin on the
top to a position I below the top coin (for some I between 0 and 100). We will
call this as i-move (thus a 0-move implies doing nothing). The proviso is that
an i-move cannot be repeated, for example once a player makes a 2-move, on subsequent
turns neither player can make a 2-move. If the gol coin happen to be on the top
when its a players turn then the player wins the game. Initially, the gold coin
is the third coin from the top. Then
a.In order to win, Alice’s first move should be a 1-move.
b.Alice has no winning strategy.
c.In order to win, Alice’s first move can be a 0-moveor a 1-move.
d.In order to win, Alice’s first move should be a 0-move.
