看完这个题，大家都懂意思吧，然后代码呢，emmmmm

#include <bits/stdc++.h>
using namespace std;
const int maxn = 1e4 + 10;
int n;
int a[maxn];
int l,r;
int maxx;
int main()
{
    //freopen("in","r",stdin);
    ios::sync_with_stdio(0);
    cin.tie(0);
    cout.tie(0);
    cin >> n;
    for(int i = 1; i <= n; i++)
        cin >> a[i];
    for(int i = 1; i <= n;i ++){
        l = i, r = i;
        while(a[l] >= a[l - 1] && l - 1 >= 1)
            l--;
        while(a[r] >= a[r + 1] && r + 1 <= n)
            r++;
        maxx = max(r - l + 1,maxx);
    }
    cout << maxx;
    return 0;
}
