Consider a hash table of size 10 with indices $\{0,1, \ldots, 9\}$, with the hash function
$$ h(x)=3 x(\bmod 10) $$
where linear probing is used to handle collisions. The hash table is initially empty and then the following sequence of keys is inserted into the hash table: 1 , $4,5,6,14,15$. The indices where the keys 14 and 15 are stored are, respectively
