一份代码，从周六提交到周一，一直是 Judgement Failed，到底什么问题啊啊啊啊啊啊啊啊

T423，代码如下

#include<bits/stdc++.h>
#define int long long
#define endl '\n'
#define FAST ios::sync_with_stdio(false);cin.tie(0);cout.tie(0);
using namespace std;

{
    return i>j;
}
double mylog(int x,int y)
{
    return log(x)/log(y);
}
long long qpow(long long a,long long b,long long mod=LLONG_MAX)
{
    if(b==0)return 1;
    if(b==1)return a;
    return qpow(a,b/2,mod)%mod*qpow(a,b/2,mod)%mod*(b&1?a:1)%mod;
}
int n,a,b,c;
void solve()
{
    a=0,b=0;
    for(int i=0;i<n;i++)
    {

        cin>>x;

    }

    {

    }
    c=a+b;
    for(int i=0;i<n;i++)
    {

        else cout<<0<<' ';

    cout<<'\n';
}
