Try this insertion sequence for testing your knowledge on extendible hashing: Using a bucket size of 3 you are to insert into an empty extendible hash structure 5 values, r1 to r5 whose bit strings after calculating the hash function are all zeros.  You are to use a mod 32 hash function for this part of the assignment.  I.e., the hash values are 5 zeros, and they are all the same.  Hint: you will need overflow buckets for this part of the assignment.
