From a given list of numbers, only the first and last numbers can be chosen
at a given point in time. There are two players 'A' & 'B'. They get to pick
up the numbers in turn. Player 'A' starts first. Pick a winning sequence of
numbers for 'A' and 'B' so that 'A' wins always, no matter how well 'B' plays.
Assume that both 'A' and 'B' picks the best numbers possible.
