Question
Consider a double hashing scheme in which the primary hash function is , and the secondary hash function is . Assume that the table size is 23. Then the address returned by probe 1 in the probe sequence (assume that the probe sequence begins at probe 0) for key value is ________.
Correct answer
13 to 13
Solution
Given:
Table size
Key Calculate hash values:
(since , )
(since , )Probe sequence formula for double hashing:
For probe 0 ():
For probe 1 ():
The address returned by probe 1 is 13.
