Sample game:

<pre>

Here's your first list : [7, 5, 8, 3, 4, 6, 9, 2, 1]

How many numbers from the left are to be reversed : 7

Here's your list now : [9, 6, 4, 3, 8, 5, 7, 2, 1]

How many numbers from the left are to be reversed : 9

Here's your list now : [1, 2, 7, 5, 8, 3, 4, 6, 9]

How many numbers from the left are to be reversed : 5

Here's your list now : [8, 5, 7, 2, 1, 3, 4, 6, 9]

How many numbers from the left are to be reversed : 8

Here's your list now : [6, 4, 3, 1, 2, 7, 5, 8, 9]

How many numbers from the left are to be reversed : 6

Here's your list now : [7, 2, 1, 3, 4, 6, 5, 8, 9]

How many numbers from the left are to be reversed : 7

Here's your list now : [5, 6, 4, 3, 1, 2, 7, 8, 9]

How many numbers from the left are to be reversed : 2

Here's your list now : [6, 5, 4, 3, 1, 2, 7, 8, 9]

How many numbers from the left are to be reversed : 6

Here's your list now : [2, 1, 3, 4, 5, 6, 7, 8, 9]

How many numbers from the left are to be reversed : 2

Here's your final list : [1, 2, 3, 4, 5, 6, 7, 8, 9]

So you've completed the game with a score of 9
