Can anybody tell me this test please?))

Hello y'all!
I don't understand what's wrong with my code.When i tested it on my own it worked perfectly).but when i've sent it, it got WA#3.Can u tell me what's wrong,PLEASE).Here's my code in C++:
int sum(long a)
{
    return a/100+(a%100)/10+a%10;
}
bool islucky(long t)
{
    long t1=t/1000,t2=t%1000,a1=sum(t1),a2=sum(t2);
    if(a1==a2)
        return true;
    else
        return false;
}
int main()
{
    long t;
    cin>>t;
    long t1,t2;
    t1=t+1;
    t2=t-1;
    if(islucky(t1)||islucky(t2))
    {
        cout<<"Yes"<<endl<<t1<<endl<<t2;

    }
    else
        cout<<"No";
    return 0;
}

use strings to represent numbers

{
    int n,a,b,c,d,e,f;
    cin>>n;
    f=n%10;
    e=(n/10)%10;
    d=(n/100)%10;
    c=(n/1000)%10;
    b=(n/10000)%10;
    a=(n/100000)%10;
    cout<<a<<endl;
    cout<<b<<endl;
    cout<<c<<endl;
    cout<<d<<endl;
    cout<<e<<endl;
    cout<<f<<endl;
    if((a+b+c)-(d+f+e)==1 || ((a+b+c)-(d+f+e)==-1))
        cout<<"yes";

Plz, could anyone explain me, what i have to do...
Even looking on the sample tests, i didnt get the task =(

I have try to solve this problem in different ways in Java and on C++ but I still have WA1
there are impossible cases 999999 000000 so I don't check overflow or negative
I can't imagine what is problem, can somebody tell me what is wrong there ?

// edit
[code was deleted]
