Hey @cbcao263
Please explain ur logic

#3

I first inserted char of first string in map and then matched with other strings and if it is present in both then I inserted in main map

#4

Say we had B E L L A , … LABEL, … A
as 3 strings
Now u put BELLA in m1
Now for 2nd string u check and put L A B E L in main
Now for 3rd string its already there so no need
So u will get ans as LABE but actual ans is A only

   for(auto itr=main.begin();itr!=main.end();itr++)

    {
        char y=itr->first;
        string x="";
        x+=y;
        res.push_back(x);
    }

Use this in ur code to get it working
And then try to debug logically

#5


sir ab shi hain?

#6

Syntatically shi h but logically u have to still work on it
Think of each string as a multiset and u have to take intersection of all sets
