    }
    
    
    void tranversePath(const vector>& graph, vector>& paths, vector path, int current, int target) {
        path.push_back(current);
        int length = graph.size();
        if(current == target) {
            paths.push_back(path);
            return;
        }
        for(int i = 0; i < graph[current].size(); i++) {
            tranversePath(graph, paths, path, graph[current][i], target);
