    c++ solution, disliking the fact that I spent a bit too long thinking about how to do this, no cause the problem explenation sucks.

    string biggerIsGreater(string w) {
    int n = w.length();
    int i = n - 2;

    while (i >= 0 && w[i] >= w[i + 1]) {
        i--;
    }

    if (i < 0) return "no answer"; 

    int j = n - 1;
    while (w[j] <= w[i]) {
        j--;
    }

    swap(w[i], w[j]);

    reverse(w.begin() + i + 1, w.end());

    return w;
}
