WebEngineering Computer Science Consider an extensible hash table that uses 4-bit hash keys and stores two records per bucket. Simulate the insertion, into an initially empty hash table, of records with (hash values of) keys 1111, 1110, 1101,..., 0001, 0000, in that order. Simulate all 16 insertions, indicating what happens after each insertion.
