    int ptr;
    
    public OrderedStream(int n) {
        streamList = new String[n];
        ptr = 0;
    }
    
    public List<String> insert(int id, String value) {
        streamList[id - 1] = value;
        
        ArrayList<String> orderedStreams = new ArrayList<String>();
        for (int i=ptr; i<streamList.length; i++) {
            if (streamList[i] == null) break;
            orderedStreams.add(streamList[i]);
            ptr++;
        }
