/*
SOLUTION : For each item we calculate separately. Separate for each number the queries into 3 regions. Anything
in middle region basically keeps higher->higher and lower->higher. so find last region-type-2. count #region-typ
e-3 after that. (region-type-1 has no effect). Also, take acnt of the initial swap.
