Just feeling my way through this one, ploddingly . . .
-- The first and last digits can be
That's 11 possible pairs ... an odd number because the first digit can't be zero.
-- For each possibility, the middle 2 digits can be anything from 00 to 99 ... 100 pairs.
-- So the total list of numbers that satisfy the conditions comprises 1,100 of them.
I don't have a lot of confidence in this derivation, because I'm not completely
sure of what you mean by 'distinct digits', so I ignored that specification.
952 of them.
An infinite amount
For each pair of such integers, find the difference between the absolute values of the two integers and allocate the sign of the bigger number to it.
None. Integers can be negative, absolute values cannot. Absiolute values can be rational or irrational fractions, integers cannot.
Find the difference between the two numbers and attach the sign that belongs to the number with the bigger absolute value.

The distance between two integers is the difference.

Yes.

-4
subract the number from the number, simple, at least that is what i found
one of the difference is HQL does not support distinct but SQL supports the distinct in the query
There are 120 of them.
