You are asked to insert the following values into the hashing table size 9: 9, 18, 19, 27, 8, 17. Use linear probing if there is a collision. Your answer will be in the form of the order of inserted elements. The order of inserted elements:: 9 18 19 - - 27 8 - 17 The order of inserted elements: 9 18 19 27 - - 17 - 8 O The order of inserted elements: 9 18 19 27 17 - - -8 O The order of inserted elements: 9 18 19 27 8 - -17 -

Given the array of size 17, and the hashing function h(x) = x%17, at which array location would data with key value 86 be stored? Assuming 35 and 69 have already been inserted in the array and the quadratic probing is used for collision. Question 10 options: 6 5 4 3
The following is a prioritised list of considerations that might impact a hash table's Big-O performance:
Best hash function will never create any collision among the hash table values. O True O False QUESTION 4 There exists a data structure to maintain a dynamic set with operations Insert(x), Delete(X) and Contains(X) that has an expected running time of O(1) per operation. O True O False
If the sizeof hash table is 11, the hash function is H(key)=(2*key+1)MOD 11，open addressing, square probing. According to the keywords sequence (19,21,10,7,23,32,17,15,11,22), please insert these keywords in the hash table from 0-10 .

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…
