Assume a Hash table has 7 slots and the hash function h(k) = k mod 7 is used. The keys 14, 3, 11, 6, 10, 4, 20, and 17 are inserted in the table with collision resolution by chaining. Assume that the keys arrive in the order shown. (a) Show the hash table obtained after inserting all 8 keys. [Show only the final table] (b) Under the assumption that each key is searched with probability 1/8, calculate expected number of...

Suppose we use the hash function h(x) = x mod 7 (i.e. h(x) is the remainder of the division of x by 7) to hash into a table with 7 slots (the slots are numbered 0, 1,…, 6) the following numbers: 32, 57, 43, 20, 28, 67, 41, 62, 91, 54. We use chaining to handle collisions. Which slot contains the longest chain?
