Hi!
I know this is the kind of topic that a lot of posts in this forum answers, but I can't get the exact information i'm looking for.
I have three colls (could be more) in which I have symbols.
Ex :
Coll 1 :
1, apple;
2, orange;
3, mango;
4, mulberry;
Coll 2 :
1, watermelon;
2, orange;
3, avocado;
4, apple;
Coll 3 :
1, orange;
2, strawberry;
3, papaya;
4, apple;
As you can see, "apple" and "orange" are in each of the colls.
I'd like to populate a new coll with only these two symbols.
Coll final :
1, apple;
2, orange;
I know there are some posts about removing the duplicates, but not so much about keeping the duplicates, and it's often about numbers, maybe I could do something with converting the symbols to ascii and itoa back when the duplicates are filtered but i can't seem to find the exact way of doing this...
Thanks in advance for your help!
