Length of those 2 vectors are essentially be same. Here task is to check the duplicates in the vector 'a' and then to check whether any duplicates are there in the same places of 'b'. If not, flag a FALSE. I above example, it is correct hence TRUE. However in general how can I implement this? Can somebody please help me?
