帮忙写注释
#include<bits/stdc++.h>using namespace std;
bitset<501000> H;//H为一个二进制数组，每个元素是一个0或者1
int n,s=0,x;
int main(){
freopen("competition.in","r",stdin);//文件输入输出
freopen("competition.out","w",stdout);
cin>>n;
H[0]=true;
for(int i=1;i<=n;i++){
cin>>x;
s+=x;
H=H | (H<<x);
}
int x=0;
for(int i=1;i<=s;i++)
if(H[i] && i <= s-i) x=i;
cout<<x<<" "<<s-x<<endl;
return 0;
}
请各位大佬写下注释，必有重谢
