6-12: Consider using a set for cleaner, more idiomatic code.The algorithm is correct and efficient. However, since the stored value in
seen_hashis never used, a set would be more appropriate and memory-efficient than a dictionary.🔎 Proposed refactor using set
def repeatedNTimes(self, nums: List[int]) -> int: - seen_hash = {} # this can solved with set as well + seen = set() for num in nums: - if num in seen_hash: + if num in seen: return num - seen_hash[num] = 1 + seen.add(num)

137-160: LGTM!The test cases are comprehensive and cover all the key scenarios including edge cases (minimum size array, all elements the same, different positions of repeated elements, and various array sizes). The test structure follows pytest conventions correctly.

Fix grammatical error in comment.
The comment has a grammar issue: "this can solved" should be "this can be solved".
🔎 Proposed fix
- seen_hash = {} # this can solved with set as well
+ seen_hash = {} # this can be solved with set as well📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In LeetCode/easy/n_repeated_element_961.py around line 7, the inline comment
reads "this can solved with set as well" which is grammatically incorrect;
update it to "this can be solved with a set as well" (or "this can also be
solved with a set") to correct grammar and improve clarity.

16-16: Fix grammatical error in comment.The grammatical error "this can solved" was already flagged in a previous review and should be corrected to "this can be solved with a set as well".

16-21: Consider using a set instead of a dictionary.The implementation correctly identifies the repeated element. However, since you only check for presence and never use the dictionary values, a set would be more idiomatic and slightly more efficient.
🔎 Proposed refactor using a set
- seen_hash = {} # this can solved with set as well + seen = set() for num in nums: - if num in seen_hash: + if num in seen: return num - seen_hash[num] = 1 + seen.add(num)

5-15: LGTM! Well-documented method signature.The class structure, method signature with type hints, and auto-generated docstring are all clear and follow Python conventions.
