WebAll steps. Final answer. Step 1/3. Answer (i): To insert each key into the hash table, we use the double hashing function h (k) to compute the initial slot and then increment by h' (k) until an empty slot is found. If the table is full, we stop inserting keys. Initially, we have an empty hash table with size m=13. Step 1: Insert 15 h (15) = 2.
