Kefa decided to make some money doing business on the Internet for exactly n days. He knows that on the i-th day (1 ≤ i ≤ n) he makes ai money. Kefa loves progress, that's why he wants to know the length of the maximum non-decreasing subsegment in sequence ai. Let us remind you that the subsegment of the sequence is its continuous fragment. A subsegment of numbers is called non-decreasing if all numbers in it follow in the non-decreasing order.
Help Kefa cope with this task!
The first line contains integer n (1 ≤ n ≤ 105).
The second line contains n integers a1, a2, ..., an (1 ≤ ai ≤ 109).
Print a single integer — the length of the maximum non-decreasing subsegment of sequence a.

In the first test the maximum non-decreasing subsegment is the numbers from the third to the fifth one.
In the second test the maximum non-decreasing subsegment is the numbers from the first to the third one.
我居然上来就想套LIS的模板。。。我*了狗。。。然后发现读错题,扫一遍就行了。。
