Description

One day, Bessie was gazing off into the distance at the beautiful
Wisconsin mountains when she wondered to herself: which mountain
is the widest one?

She decided to take N (1 <= N <= 100,000) equally-spaced height
measurements H_i (1 <= H_i <= 1,000,000,000) sequentially along the
horizon using her new Acme Long Distance Geoaltimeter.

A mountain is defined to be a consecutive sequence of H_i values
which increases (or stays the same) and then decreases (or stays
the same), e.g., 2, 3, 3, 5, 4, 4, 1. It is possible for a mountain
on the edge of her field of vision only to increase or only to
decrease in height, as well.

The width of a mountain is the number of measurements it encompasses.
Help Bessie identify the widest mountain.

Here's a simple example of a typical horizon:

*******                   *
*********                 ***
**********               *****

aaaaaa                   ccccccccccccccccccccc eeeeeee    ggggggggg
bbbbbbbbbbbbbbbbbbbbbbbbbbbb             ddddd ffffffffff  hhhhhhhhh

The mountains are marked 'a', 'b', etc. Obviously, mountain b is
widest with width 28. The mountain on the left has width 6 for the

Input

* Line 1: A single integer: N

widest mountain.
