    My logical brain took over and I didn't even second thought that it can be easily done with std::min(p / 2, n / 2 - p / 2);

    int pageCount(int numOfPages, int pageNum) {
    int count1 = 0;
    int count2 = 0;
    if (numOfPages == pageNum || pageNum == 1){
        return 0;
    }
    for (int i = 2; i <= numOfPages; i+=2){
        count1++;
        if (i == pageNum || i+1 == pageNum){
            break;
        }
    }
    if (numOfPages%2 != 0){
        count2--;
        for (int i = numOfPages; i >= 2; i-=2){
            count2++;
            if (i == pageNum || i-1 == pageNum){
                break;
            }
        }
    } else {
        for (int i = numOfPages-1; i >= 2; i-=2){
            count2++;
            if (i == pageNum || i-1 == pageNum){
                break;
            }
        }
    }
    return (count1 > count2) ? count2 : count1;
}
