Question description


for example in one of the past paper i am practicing, their is this question...

1) a) For a 11-bucket hash table, primary hash function h1 and secondary hash function h2,
show how the six objects Q, W, E, R, T, Y are inserted into an initially empty table
when using double hashing and when the values of the two hash functions are as
shown in the table below.
object Q W E R T Y
h1 8 10 0 8 9 9
h2 5 1 2 3 4 5
For each object show the positions probed before insertion. Show the resulting hash
table (as an array of objects)

The answer for this question is...

probed
Q 8 W 10 E 0 R 8, 0, 3 T 9 Y 9, 3, 8, 2
hash table
0 1 2 3 4 5 6 7 8 9 10 E Y R Q T W


I cant seem to understand the answer and very confused with the double hashing algorithm, please help out.

thanks.
