Given a list of integers, how can I best find an integer that is not in the list?
The list can potentially be very large, and the integers might be large (i.e. BigIntegers, not just 32-bit ints).
If it makes any difference, the list is "probably" sorted...

Return v_i + 1.
That are not consecutive.

Write a branchless function that returns 0, 1, or 2 if the difference between two signed integers is zero, negative, or positive.
Here's a version with branching:
int Compare(int x, int y) { int diff = x - y; if (diff == 0) return 0; else if (diff <...

In it there are many (very very many) places where I access a global one dimensional UBYTE array using a variety of integer indexes. Occasionally this index may be negative...

I would put blatantly wrong values, so that you get a clearly wrong value could ever be negative; it's obvious that they will return an incorrect value so surely you shouldn't let the index to go negative....
