<pre>Given a list of numbers, try to put them into ascending order
by sequentially reversing everything left of a point you choose
in the array. Try to do it in as few reversals as possible.
No input will quit the game.
Position Num: 1 2 3 4 5 6 7 8 9
Current List: 1 6 3 2 8 7 9 4 5 Enter position of reversal limit: 7
Current List: 9 7 8 2 3 6 1 4 5 Enter position of reversal limit: 9
Current List: 5 4 1 6 3 2 8 7 9 Enter position of reversal limit: 7
Current List: 8 2 3 6 1 4 5 7 9 Enter position of reversal limit: 8
Current List: 7 5 4 1 6 3 2 8 9 Enter position of reversal limit: 7
Current List: 2 3 6 1 4 5 7 8 9 Enter position of reversal limit: 3
Current List: 6 3 2 1 4 5 7 8 9 Enter position of reversal limit: 6
Current List: 5 4 1 2 3 6 7 8 9 Enter position of reversal limit: 5
Current List: 3 2 1 4 5 6 7 8 9 Enter position of reversal limit: 3
Current List: 1 2 3 4 5 6 7 8 9
Congratulations! You win! Only 9 reversals.</pre>
