Suppose you have a closed hash table with 500 slots, and there are currently 400 records in the hash table. Approximately how many memory accesses, on average, would you expect upon inserting the next record into the table, assuming a "good" (near optimal) hash function and probe function?

If a bucket is full, use the next (sequential) bucket that contains a free slot.Using quadratic probing, what would be the answer for the following questions if you insert the following keys in sequence: 10, 17, 24, 31, 21, 19. (N = 7) While doing the insertions keep track of the number of collisions for each key and get the final configuration of the structure. Use the following quadratic hashing function: ((x mod 7) + j²) mod 7. What is the final configuration of the hash table? Use the indices from 0 to 6 to report where each key will be mapped. If the position has no value use the word empty. For example, if the final configuration is 10,17,24,31,21,19 (starting from index 0), your answer in the box should be 10,17,24,31,21,19,empty. Please don't use blank spaces or quotes to separate the values. Report the number of collisions for each key using the order of insertion. For example, if you answer as 0,1,3,1,0,1, this means that you found 0 collisions for key 3, 1 collision for key 10, 3 collisions for key 17, 1 collision for key 24, 0 collisions…This section provides a prioritized list of factors that affect the Big-O performance of a hash table:
- Given a sequence of 5 keys < 53, 66, 32, 41, 88 > for searching task: a) Given the hash function H(k) = (3.k) mod 7, insert the keys above according to its original order (from left to right) into a hash table of 7 slots. Indicate the cases of collision.

Clearly show your answer for each identified case.

To improve the time complexity of the operations performed on the table, a special AVAILABLE object is used to mark a location when an item is removed from the location. Assuming that all keys are positive integers, the following two techniques were suggested instead of marking the location as AVAILABLE: i) When an entry is removed, instead of marking its location in the table as AVAILABLE, indicate the key in the location as the negative value of the removed key (e.g., if the removed key was 16, indicate the key as -16). Searching for an entry with the removed key would then terminate once a negative value of the key is found (instead of continuing to search if AVAILABLE is used). ii) Instead of using AVAILABLE, find a key in the table that should have been placed in the location of the removed entry, then place that key (the entire entry of course) in that location (instead of setting the location as AVAILABLE). The motive is to…Consider the following sequence of keys to be inserted in turn in a hash table of size 7 that uses quadratic probing to resolve collisions (only use +i2 in probing, and do not use -i2 in probing) : 19, 26, 3, 20, 2, 10 Select the choice that shows what the hash table looks like after all keys are inserted (X indicates an empty slot). Question 29 options: [20, 3, X, 26, x, 19, 2] [x, 2, 3, 20, X, 19, 26] [20, X, 2, 3, x, 19, 26] [x, 3, 2, 26, X, 19, 20] [20, X, 2, 3, 19, x, 26]
