I did this but still tests 10,12,13 fail due to timeout. Please help

my solution :

static List freqQuery(List queries) {

    HashMap<Integer,Integer> hash = new HashMap<Integer,Integer>();
    List<Integer> retList = new ArrayList<Integer>();

    for(int i=0;i<queries.size();i++)
    {
        int op = queries.get(i)[0];
        int num = queries.get(i)[1];
        if(op==1)
        {
            if(!hash.containsKey(num))
                hash.put(num,1);
            else
                hash.put(num,hash.get(num)+1);
        }
        else
        if(op==2)
        {
            if(hash.containsKey(num))
            {
                if(hash.get(num)<=1)
                    hash.remove(num);
                else
                    hash.put(num,hash.get(num)-1);
            }

        }
        else
        if(op==3)
        {
            if(hash.containsValue(num)){
                retList.add(1);
            }
            else
                retList.add(0);

        }
    }

    return retList;
}
