从文本中删除第一个重复字符串

def remove_first_duplicate(text):
    words = text.split()  # 将文本分割成单词列表
    word_count = {}  # 记录单词出现次数的字典

    # 统计每个单词的出现次数
    for word in words:
        if word in word_count:
            word_count[word] += 1
        else:
            word_count[word] = 1

    # 找到第一个重复的单词
    duplicate_index = None
    for i, word in enumerate(words):
        if word_count[word] > 1:
            duplicate_index = i
            break

    # 删除第一个重复的单词
    if duplicate_index is not None:
        words.pop(duplicate_index)

    # 重新组合文本
    new_text = ' '.join(words)
    return new_text

# 示例用法
text = "This is a test test string."
new_text = remove_first_duplicate(text)
print(new_text)
