Category: CodingEval type: Shard evalQuestions: 164Shards: 13Runs: 52

Dry-run first:

lmx eval shard humaneval-plus --base-url http://localhost:8000 --questions 116 --dry-run

Then submit with a real model and hardware profile:

lmx eval shard humaneval-plus --base-url http://localhost:8000 --questions 116 --model <hfId> --hardware hardware.json --submit

Scores are pooled by unique question_id; the leaderboard is ranked by Wilson 95% lower bound.

        # Actually, let me try: for any number, compute popcount of its binary representation.
        # For negative numbers in Python, bin(-6) = '-0b110'. If we count ones in '110', that's 2.

        # -2: popcount(10) = 1, value -2

        # So that doesn't work. Let me try another approach: maybe negative numbers are sorted purely by value, ignoring popcount?

    # A character is part of a word if it is preceded by another non-space character
    # or if it is the first character of the string.
    # However, the condition "not a part of a word" implies it must be isolated.
    # Based on examples:
    # "apple pi e" -> 'e' is preceded by space, so it's a standalone word -> True
    # "apple pie" -> 'e' is preceded by 'i', so it's part of "pie" -> False
    # "apple pi e " -> last char is space -> False (handled by isalpha check)
    
    # We need to check the character immediately before the last one.
    # If the string has only one character, it is considered a word by itself?
    # Let's re-read: "is not a part of a word".
    # If txt = "a", is 'a' part of a word? Yes, it is a word.
    # But the example "apple pi e" returns True. The 'e' is a word of length 1.
    # Wait, the prompt says "is not a part of a word".
    # Usually, a single letter is a word.
    # Let's look at the logic again.
    # "apple pie" -> last char 'e'. Previous is 'i'. 'ie' is part of "pie". False.
    # "apple pi e" -> last char 'e'. Previous is ' '. 'e' is a separate word. True.
    # "apple pi e " -> last char ' '. False.
    
    # What if the string is just "a"?
    # If "a" is a word, then it is part of a word. So it should be False?
    # Or does "part of a word" mean "part of a word with length > 1"?
    # The phrasing "is not a part of a word" is slightly ambiguous.
    # However, looking at the examples:
    # "apple pi e" -> True. The 'e' is a word.
    # If the condition was "is a word", it would be True.
    # If the condition is "is not part of a word", maybe it means "is not attached to other letters"?
    # Let's assume "part of a word" means "connected to other letters".
    # So if the previous character is a letter, it's part of a word.
    # If the previous character is a space (or it's the start of the string), it's not "part" of a larger word.
    # But if it's the start of the string, is it a word? Yes.
    # Is a single letter "part of a word"? Technically yes, it is the whole word.
    # But in the context of these coding puzzles, "part of a word" usually implies "surrounded by letters".
    # Let's test the hypothesis: Return True if last char is alpha AND (len < 2 OR txt[-2] == ' ').
    
    if len(txt) == 1:
        # If the string is just one letter, is it "part of a word"?
        # If we follow the logic of "apple pi e", 'e' is a word.
        # If the requirement is "not a part of a word", maybe it means "not attached to a previous letter".
        # Let's assume the intended logic is: The last character must be an alpha, and it must be preceded by a space (or be the first char).
        # Wait, if txt = "a", is it True or False?
        # If I assume "part of a word" means "connected to other letters", then "a" is not connected to others.
        # But "a" IS a word.
        # Let's look at the example "apple pi e". The 'e' is a word. The function returns True.
        # So if it IS a word, it returns True?
        # But the text says "is not a part of a word".
