怎么回事呀!!!!!!!!!!!!!!!!!!!!

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n,a[1000000],m=0,v=0;
	cin>>n;
	for(int i=1;i<=n;i++){
		cin>>a[i];
		if(a[i]>a[i+1]&&a[i==1]){
			m=a[i]+=a[i+1];
		}else if(a[i]>a[i+1]&&a[i>1]){
			int b=a[i]+a[i-1];
			int c=a[i]+a[i+1];
			if(b>c){
				m=b;
				
			}else{
				m=c;
			}
			if(a[i]<a[i+1]){
				v=a[i]+a[i+1];
			}else if(a[i]>a[i+1]){
				break;
			}
			cout<<v<<endl<<m;
		}
	}
