Assume data is to be stored in a hash table using the following key sequence: 76, 84, 15, 31, 5, 21 Assume the hash table size is 8, the hash function used is the modulo function i.e. h(key) = key % table_size, and collisions are handled using linear probing. What's the content of the table after all keys are mapped to the hash table? List keys starting from table index 0 and on. Separate numbers by a comma and a single space, and indicate an empty slot with an X. If a data item can't be stored, indicate so.

For a hash table of size 23, the hash function used is h1(key)=key%23. Initially the table contains a single key stored in the table at location 15. If double hashing is used, and h2(key) = 7 – key%7, where will the next 3 keys (key1=15, key2=84, key3=383) that hash to location 15 be stored?

1. An open hashing scheme requires the use of random access ( true /false ). 2. A good hashing function should ___ distribute the records amongthe buckets. 3. For an open hashing scheme with 100 buckets and 4000 records,the average number of record reads to locate a record is equal to___.
Suppose that we are maintaining a table using l inear hashing , with the hash function h(x) = x mod 8. Each block can store up to 3 records. The constraint on the number of buckets is R <= 2.5N, where R is the total number of records in the structure, and N is the number of buckets. Construct the hash structure after the records with the following keys have been inserted: (2, 3, 5, 7, 11, 17, 19, 23, 29, 31) Construct the final structure. Be sure to indicate the value i (the number of hash bits being used), N, and R. Which of the following is true? Group of answer choices Key values 2 and 5 are in the same block. Key value 7 is in a block by itself. Key values 7 and 17 are in the same block. Key values 17, 5, and 29 are in the same block.
