思路差不多就是暴力模拟，可RE的厉害

#include<bits/stdc++.h>
using namespace std;
vector<int> a,b;
int main(){
    int n,big=INT_MIN,tmp;
    vector<int>::iterator bigi=a.begin(),ii=a.begin();
    cin>>n;
    for(int i=0;i<n;i++){
        cin>>tmp;
        a.push_back(tmp);
        b.push_back(tmp);
        if(a[i]>big){
            big=a[i];
            bigi=ii;
        }
        ii++;
    }
    ii=a.begin();
    sort(b.begin(),b.end());
    a.erase(bigi);
    a.push_back(big);
    for(int i=0;i<n;i++){
        if(a[i]!=b[i]){
            cout<<"NO"<<endl;
            return 0;
        }
    }
    cout<<"YES"<<endl;
}

另外编译是clang++的警告看不懂（它还会直接把这个源代码删了）
