It displays -7 . (yet when I add one more "al.Reverse()" into the
code, it displays 4 )
From the documentation (RTFM is good)
Return Value
The zero-based index of value in the sorted ArrayList, if value is
found; otherwise, a negative number, which is the bitwise complement of
the index of the next element that is larger than value or, if there is
no larger element, the bitwise complement of Count.
