Fetching random row from each group in oracle

I have a table which has row, title, code and store as columns.

I have to group by code and store.

Assume table contains these rows.

Row        Title       Code        Store
      
1       title1      abcd        store1
2       title2      abcd        store1
3       title3      abcd        store1
4       title1      efgh        store2
5       titlex      efgh        store2

select code,store,count(*) from table
group by code,store order by count(*) desc;

It will give :

abcd        store1        3
efgh        store2    2

Now how can we get one random row from each group. For example it should give

Row       Title       Code        Store

2       title2       abcd            store1
5       titlex       efgh            store2

any one of the record from each group.
