SpellBob Problem

What could be the possible error in my code, I have tested almost all edge cases and a couple of the prescribed test cases also. Attached herewith is my code:

#include <bits/stdc++.h>
using namespace std;

#define NEWLINE "\n";
typedef long long ll;

int count(string s, char c)
{
    int res = 0;

    for (int i=0;i<s.length();i++)
        if (s[i] == c)
            res++;
    return res;
}

int main()
{
    ios::sync_with_stdio(false);

    ll T;
    cin >> T;

    string faceUp, faceDown;

    while(T--)
    {
        cin >> faceUp;
        cin >> faceDown;

        char k = 'b';
        char h = 'o';
        int faceUB = count(faceUp, k);
        int faceUO = count(faceUp, h);
        int faceDB = count(faceDown, k);
        int faceDO = count(faceDown, h);

        if(faceUB + faceDB < 2 || faceUO + faceDO  < 1)
        {
            cout << "no" << NEWLINE;
            break;
        }

        bool flag = true;

        if(faceUp == "bob" || faceUp == "obb" || faceUp == "bbo")
        {
            cout << "yes" << NEWLINE;
            continue;
        }
        else if(faceDown == "bob" || faceDown == "obb" || faceDown == "bbo")
        {
            cout << "yes" << NEWLINE;
            continue;
        }

        vector<int> up = {-1, -2, -3}, down = {-4, -5, -6};
        int counterUp = 0, counterDown = 0;

        for(int i = 0; i < 3; i++)
        {
            if(faceUp[i] != 'b' && faceUp[i] != 'o')
                up[counterUp] = i;
            counterUp++;
        }
        for(int z = 0; z < 3; z++)
        {
            if(faceDown[z] != 'b' && faceDown[z] != 'o')
                down[counterDown] = z;
            counterDown++;
        }

        for(int j = 0; j < 3; j++)
        {
            if(up[j] == down[j])
            {
                cout << "no" << NEWLINE;
                flag = false;
                break;
            }
        }
        if(!flag)
            continue;

        cout << "yes" << NEWLINE;
    }
    return 0;
}
