There are N buildings stand along the horizon line. Each building are represented as a vertical segment with two end points at (i, 0) and (i, Ai). There are M queries in total. For each query, we wonder know how many buildings you can see if you stand at (0, h).
... N, M ≤ 106, both Ai and h is positive integer and ≤ 109.
Input
N
A1 A2 ... An
M
(here following the M queries.)
