Question

1. Hashing and Linear Probing for Collision

Write on a piece of paper the contents of the resulting has table after inserting these keys. The table should contain 10 elements, with only one address that is left open, i.e., it is not occupied by any key. Answer the questions below by filling up the blanks. 4. Which key value was stored in address (array index) 8? 5. The value of H(k) is called k's home address. How many keys were not stored in their respective home addresses? 6. In which address was key 380237 stored?

Consider the following scenario/assumptions: • A hash table can store at most 11 elements. Indices are numbered from 0 to 10. It is currently empty (no elements yet). • The hashing function is defined as H(k) = k % 11 • The collision resolution technique is Linear Probing. Insert the following keys in the hash table in the sequence that they appear below: • 160237 • 270238 • 380237 • 490240 • 600237 • 710242 • 820237 • 930244 • 1040237 • 1150246
