A number is initially written on the board with 98 eights. You are allowed to perform one of the following operations on this number:
1) Replace the original number with the difference between the number obtained by removing the last three digits and the number formed by its last three digits (possibly with leading zeros; the difference is taken as the absolute value, subtracting the smaller number from the larger one).
2) If the original number contains a digit that is not 9 and has two neighboring digits that are greater than 0, you can increase this digit by 1 and decrease the neighboring digits by 1 each. If leading zeros appear in the process, they are discarded.

In the end, a two-digit number remains. What is this number?
