Hey @shivammishra2408

            int minimum=min(n1,min(n2,n3)); //corrected this ,this was giving error
#4

There is something wrong in my logic too. Can you please check that.

#5 
            int minimum=min(n1,min(n2,n3)); //corrected this ,this was giving error
            
            for(int i=0;i<n1;i++){ //<n1 here because traversig on A
                
                if( a[A[i]] && b[A[i]] && c[A[i]] ){ //updated this
                    a[A[i]]=0;b[A[i]]=0;c[A[i]]=0; //added this because once added dont have to add again the same element
                    v.push_back(A[i]);
                }
            }

If this resolves ur query then please mark it as resolved :slight_smile:
