CodeForces 580A Kefa and First Steps

题意：求最长不递减子序列

思路：直接扫一遍就好了...

#include<bits/stdc++.h>
using namespace std;
const int maxn = 1e5+6;
int ans = 0;
int a[maxn];
int anss = 0;
int main()
{
int n;
scanf("%d",&n);
for (int i = 1;i<=n;i++)
scanf("%d",&a[i]);
for (int i = 2;i<=n;i++)
{
if (a[i]>=a[i-1])
{
anss++;
ans = max(ans,anss);
}
else
anss=0;
}
printf("%d\n",ans+1);
}

Description

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 sequenceai.
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!

Input

The first line contains integer n (1 ≤ n ≤ 105).

The second line contains n integers a1,  a2,  ...,  an (1 ≤ ai ≤ 109).

Output

Print a single integer — the length of the maximum non-decreasing subsegment of sequence a.

Hint

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.
