160-160: The
getDeletedKey()method is marked asconst, which implies that it should not modify the object state. However, the summary mentions that the return type ofgetDeletedKey()has been changed to non-const. This discrepancy needs to be resolved. If the intention is to allow modification, theconstqualifier should be removed. Otherwise, the summary should be updated to reflect the actual change.202-202: The summary states that

- 91-94: The addition of the
empty()function is a good enhancement for usability. It directly calls the underlying_map.empty()which is the correct and efficient way to check if the container is empty.

The empty() function should directly call Hash::empty() instead of comparing size() to zero for efficiency reasons. This change was correctly made in the Map class but not in the Set class.

The previous comment about the at() function implementation is still valid. The current implementation will lead to undefined behavior if the key is not present. It should be corrected to use the at() function provided by the underlying map.

The previous comment about the insert function taking two parameters const K k, V v is still valid. The key should be taken by const reference to avoid unnecessary copying for non-primitive types.

The empty() function in the Set class within the dense::hash namespace should also directly call Hash::empty() instead of comparing size() to zero for efficiency reasons, as previously mentioned for the Set class in the hash namespace.

The at() function implementation issue mentioned earlier for the Map class in the hash namespace also applies here in the dense::hash namespace. It should be corrected to use the at() function provided by the underlying map to prevent undefined behavior.
