The question presents a hash map with a small, manually filled table and asks what hash_map._find_slot(5, 'keyM') will return when probing begins at index 5.
First, note the table contents by index (0 to 6):
0 -> 'keyX', 1 -> 'keyY', 2 -> 'keyZ', 3 -> 'keyW', 4 -> None, 5 -> 'keyQ', 6 -> 'keyR'.
The probe starts at index 5 due to the provided initial index of 5.
- Index 5 contains 'keyQ', which does not match the search key 'keyM'.
- Move to the next slot (linear probing): index 6 contains 'keyR', which also does not match 'keyM'.
- Continue probing: wrap around to index 0, which contains 'keyX' (not a match).
- Next, index 1 has 'keyY' (not a match).
- Then index 2 has 'keyZ' (not a match).
- Then index 3 has 'keyW' (not a match).
- Finally, index 4 is None, i.e., the first empty slot encountered during probing.
In many probing implementations, encountering an empty slot indicates the key is not present and provides the insertion/slot context; thus the function would return a tuple indicating the key was not found and the index of the first available slot, which is 4.
Evaluating the other options:
- Option 2: (True, 4) claims a found status is True, which is inconsistent with the absence of a matching key in the scanned slots; the key is not found.
- Option 3: (True, 5) asserts a match at index 5, but index 5 holds 'keyQ', not 'keyM'.
- Option 4: (False, 6) suggests wrapping around and stopping at 6, but the probing would continue until it hits the first empty slot at 4, not stop at 6.
Thus, the reasoning above supports that the probe fails to find 'keyM' and returns the first empty slot encountered, which is index 4.

HT_Rev_6 A key 48 is to be inserted into a hash table using the hash function h(k)=k mod 10, open addressing, and linear probing for collision handling. Given the current state of the hash table below, where will key 48 be stored?

HTables_3 Double hashing is a form of open addressing.

HTables_8 During open addressing, if the number of probes exceeds 1, expected run time complexity of the hash table becomes O(____). (number of probes = k, size of table =n)
