1. If h(x) is a hash function and m is odd (the table size) does

h'(x, i) = (h(x) + i*2) % m

define a valid probe sequence?  Recall, that the main requirement we have for a valid probe sequence is that it visit all of the slots in the table.

2. Assuming it's valid, given:
- h(x) = x % m
- h'(x, i) = (h(x) + i*2) % m
- m = 9

draw the table after inserting the following values:

9, 18, 4, 11, 17, 8
