- 12) Chain Length Homework If N items are inserted into a hash table of size H, what is the expected average chain length?Extendible hash index:Consider the Extendible Hashing index shown in figure below: Show the state of the index after each operation:a) Insertion of entry 1b) Insertion of entry 23c) Deletion of entry 30 draw the figures separately for a, b and cYou're tracking information on rocket launches. Each launch is assigned a number from 1000 to 100000. There will probably be around 5000 launches, and you're using a hashing algorithm that divides the highest possible number of launches by the expected number of launches. What is the hashing algorithm key in this situation? a. 200 b. 20 c. 500000 d. 5000000
- Suppose you have a hash table of size N = 64, and you are using quadratic probing. The keys in your hash are 4-digit integers (0000 through 9999) and your hash function is h(k) = (the sum of the digits in k). Assuming keys are uniformly random over the range 0000 to 9999, is this a good hash function? (Answer true for yes, false for no). True FalseLinear hash index:Consider the Extendible Hashing index shown in figure below.A bucket is split each time an overflow page gets created Show the state of the index after each operation:a) Insertion of entry 2b) Insertion of entry 40c) Insertion of entry 39A hash table with non-negative integer keys has a modulo hash function of key % 15.

- 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…Using double Hashing, insert items with keys: 69, 86, 33, 47, 17, 55 into an empty hash table. tableSize: 7 hash1(x) = x mod tableSize. hash₂(x) = R-(x mod R), R is a prime number smaller than tableSize hash1(x) + hash2(x) mod tableSizeThe following hash table uses linear probing for collision resolution and the hash code value calculation simply returns the full integer value of the key.
