查找字符串python中最长的重复片段

def find_longest_duplicate(string):
    duplicates = []
    for i in range(len(string) - 1):
        for j in range(i + 1, len(string)):
            substring = string[i:j]
            if substring in string[j:]:
                duplicates.append(substring)
    longest_duplicate = max(duplicates, key=len)
    return longest_duplicate

# 示例用法
string = "ababcabcdabcde"
longest_duplicate = find_longest_duplicate(string)
print("最长的重复片段：", longest_duplicate)

最长的重复片段： abc
