lli val = abs(val[x]-val[y]);
       ^ At this point, you've introduced a name "val", of type "long long int".
           So "val[x]" is trying to index into a variable of type long long int!

Use a different name e.g.

            lli value = abs(val[x]-val[y]);
            if(value<=mid)
            {
                dsu.Union(x,y);
            }
