answer:Here's how you can implement this using a Python dictionary: ```python def find_first_duplicate(arr): seen = {} for i, num in enumerate(arr): if num in seen: seen[num]['num_occurrences'] += 1 else: seen[num] = {'first_occurrence': i, 'num_occurrences': 1} for num, info in seen.items(): if info['num_occurrences'] > 1: return { 'element': num, 'first_occurrence': info['first_occurrence'], 'num_occurrences': info['num_occurrences'] } return None # or any other special value to indicate no duplicates # Test the function arr = [2, 5, 3, 2, 5, 1, 5] result = find_first_duplicate(arr) print(result) ``` However, this implementation returns the first duplicate it encounters in the dictionary iteration, which is not necessarily the first duplicate in the original array. If you want to ensure that you get the first duplicate from the original array, you need to modify the function to keep track of the first duplicate as it iterates through the array. Here's a modified implementation: ```python def find_first_duplicate(arr): seen = {} first_duplicate = None for i, num in enumerate(arr): if num in seen: seen[num]['num_occurrences'] += 1 if first_duplicate is None or seen[num]['first_occurrence'] < first_duplicate['first_occurrence']: first_duplicate = { 'element': num, 'first_occurrence': seen[num]['first_occurrence'], 'num_occurrences': seen[num]['num_occurrences'] } else: seen[num] = {'first_occurrence': i, 'num_occurrences': 1} return first_duplicate # returns None if no duplicates are found # Test the function arr = [2, 5, 3, 2, 5, 1, 5] result = find_first_duplicate(arr) print(result) ``` In this modified implementation, the function checks if a number is already in the `seen` dictionary. If it is, and it's the first duplicate encountered so far, the function updates the `first_duplicate` variable. At the end of the function, `first_duplicate` will hold the first duplicate from the original array. If no duplicates are found, `first_duplicate` will be `None`.

answer:Am votat astfel în favoarea textului. Here is the translation step by step: 1. Identify keywords and phrases in the original English text: I have, therefore, voted, in favour, of the text. 2. Translate each keyword/phrase into Romanian: - I have -> Am - therefore -> astfel - voted -> votat - in favour -> în favoarea - of the text -> textului 3. Arrange the translated words/phrases to form a coherent sentence in Romanian: Am votat astfel în favoarea textului. The justification behind these steps is to ensure an accurate and coherent translation of the text.
