The operation HashRemove(valsTable, 18) is performed. Ex: 1, 2, 3 What is the specific sequence of buckets probed by HashSearch(valTable, 18)? (commas between values) What is the specific sequence of buckets probed by HashSearch(valTable, 30)? (commas between values)arrow_forward3. (A) Show the result when putting the keys 19,12,14,13,9 into a hash table of size 7, usingHashing with Linear Probing. The hash function is hash(k) = k mod 7. Don’t resize.(B) Continuing from part A, show the result after deleting 19.arrow_forwardWhat is the time complexity for appending an item to a hash table with Open Addressing in worst case? Explain.arrow_forward
- A hash table with ordered linear probing maintains an order among keys considered during the rehashing process. When the keys are encountered, say, in increasing order, the performance of a failed lookup approaches that of a successful search. Describe how a key might be inserted into the ordered sequence of values that compete for the same initial table entryarrow_forwardHow many linked lists does a chaining hash table of size T have in total? To what extent does Separate Chaining's hash table accommodate primitive data types?arrow_forwardSuppose that the keys A through G, with the hash values given below, are insertedin some order into an initially empty table of size 7 using a linear-probing table (withno resizing for this problem). Which of the following could not possibly result frominserting these keys?a. E F G A C B Db. C E B G F D Ac. B D F A C E Gd. C G B A D E Fe. F G B D A C Ef. G E C A D B FGive the minimum and the maximum number of probes that could be required tobuild a table of size 7 with these keys, and an insertion order that justifies your answer.arrow_forward
