Select how many digits from the left to reverse.
The list is: [3, 4, 9, 7, 6, 1, 5, 8, 2] ==> How many digits to reverse? 8
The list is: [8, 5, 1, 6, 7, 9, 4, 3, 2] ==> How many digits to reverse? 5
The list is: [7, 6, 1, 5, 8, 9, 4, 3, 2] ==> How many digits to reverse? 4
The list is: [5, 1, 6, 7, 8, 9, 4, 3, 2] ==> How many digits to reverse? 2
The list is: [1, 5, 6, 7, 8, 9, 4, 3, 2] ==> How many digits to reverse? 9
The list is: [2, 3, 4, 9, 8, 7, 6, 5, 1] ==> How many digits to reverse? 8
The list is: [5, 6, 7, 8, 9, 4, 3, 2, 1] ==> How many digits to reverse? 5
The list is: [9, 8, 7, 6, 5, 4, 3, 2, 1] ==> How many digits to reverse? 9
The list is: [1, 2, 3, 4, 5, 6, 7, 8, 9].
