Consider a double hashing scheme in which the primary hash function is

h

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 k=90 is _______.

h

_{1}(k)=k mod 23, and the secondary hash function is h_{2}(k)=1+(k mod 19).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 k=90 is _______.
