Hello KAN I have sent a message to you in DMs Would it be possible to review my message ? Its very urgent. Thanks

Hello MikeMirzayanov could you please look into the message i have sent you

To explain better what happened, I'm posting my solution method solve()

void solve(){
    int N;
    cin>>N;
    string S;
    cin>> S;
    if(N==1){
        cout<<"Bob"<<endl;
        return;
    }
    int z=0,o=0;
    for(int i=0;i<N;i++){
        if(S[i]=='0') z++;
        else o++;
    }
    for(int i=0;i<N-1;i++){
        if(S[i]>S[i+1]) break;
        if(i==N-2){
            cout<<"Bob"<<endl;
            return;
        }
    }
    cout<<"Alice"<<endl;
    vi A;
    for(int i=0;i<z;i++) if(S[i]=='1') A.push_back(i+1);
    for(int i=z;i<N;i++) if(S[i]=='0') A.push_back(i+1);
    cout<<A.size()<<endl;
    P(A);
    cout<<"\n";
    return;
}

This is the one which led to correct submission

void solve(){
    int N;
    cin>>N;
    string S;
    cin>> S;
    if(N==1){
        cout<<"BOB"<<endl;
        return;
    }
    int z=0,o=0;
    for(int i=0;i<N;i++){
        if(S[i]=='0') z++;
        else o++;
    }
    for(int i=0;i<N-1;i++){
        if(S[i]>S[i+1]) break;
        if(i==N-2){
            cout<<"Bob"<<endl;
            return;
        }
    }
    cout<<"Alice"<<endl;
    vi A;
    for(int i=0;i<z;i++) if(S[i]=='1') A.push_back(i+1);
    for(int i=z;i<N;i++) if(S[i]=='0') A.push_back(i+1);
    cout<<A.size()<<endl;
    P(A);
    cout<<"\n";
    return;
}

And this led to incorrect submission

My code was designed such that in test case 1, it never prints "BOB" so thats why it passed test case 1 but not test case-2 despite the correct logic

Dear Organizers Ita a humble request that if in Alice/Bob questions, we need to worry about the cases and the checker is CASE SENSITIVE, then it should be highly emphasized. It took me an HOUR to solve C, not because of the logic, but because I didnt realize that I need to change "BOB" in one place to "Bob" for it to work. Such questions never had this condition of case sensitivity at all. And this change Really hindered my performance.

That guy gave QuantFest Regionals Under direct supervision of 2 core members of the IICPC organization at IIT Bombay, and he stood 25th overall in coding round with full honesty. Not to mention he had also sat through an interview screening round before being reinstated into the prelims ranklist and was allowed to appear for

I have worked with him for several months now and know how good he is in mathematics and competitive programming.
