你给出的代码旨在解决一个关于摩尔斯电码的问题，比如 [LeetCode 804. Unique Morse Code Words](https://leetcode.com/problems/unique-morse-code-words/)。该问题要求将一组单词转换为摩尔斯电码，并统计其中有多少个**不同的摩尔斯电码表示**。 不过，你当前的代码中存在一些错误，特别是 `sovle` 函数中的逻辑错误和函数调用方式。我将为你详细解释并提供修正后的代码。 --- ### ✅ 正确的实现如下： ```python morses = [".-","-...","-.-.","-..",".","..-.","--.","....","..", ".---","-.-",".-..","--","-.","---",".--.","--.-",".-.", "...","-","..-","...-",".--","-..-","-.--","--.."] def uniqueMorseRepresentations(words): # 使用集合存储不同的摩尔斯电码 morse_set = set() for word in words: # 将每个字母转换为其对应的摩尔斯电码 morse_code = ''.join(morses[ord(char) - ord('a')] for char in word) morse_set.add(morse_code) return len(morse_set) # 测试数据 words = ["gin", "zen", "gig", "msg"] print(uniqueMorseRepresentations(words)) # 输出: 2 ``` --- ### 🔍 代码解释： 1. **morses 列表**：存储了从 'a' 到 'z' 的摩尔斯电码。 2. **uniqueMorseRepresentations 函数**： - 接收一个字符串列表 `words`。 - 初始化一个空集合 `morse_set` 用于存储唯一的摩尔斯电码。 - 遍历每个单词 `word`，然后对每个字母进行转换。 - 使用 `ord(char) - ord('a')` 找到字母在 `morses` 列表中的索引。 - 将转换后的摩尔斯电码字符串加入集合。 3. 最后返回集合的长度，即不同的摩尔斯电码数量。 --- ### ❌ 原始代码问题： - `sovle` 函数中写成了 `for word in words_str`，但 `words_str` 是一个字符串，不是单词列表。 - `get_morses(words_str)` 应该是 `get_morses(word)`。 - `words = "GIN zen gig msg"` 没有被正确拆分成单词列表。 --- ### ✅ 如果你希望用原始方式修复，可以这样改： ```python morses = [".-","-...","-.-.","-..",".","..-.","--.","....","..",".---", "-.-",".-..","--","-.","---",".--.","--.-",".-.","...","-", "..-","...-",".--","-..-","-.--","--.."] def get_morses(word): morses_words_str = "" for letter in word.lower(): morses_words_str += morses[ord(letter) - 97] return morses_words_str def solve(words_str): words = words_str.split() # 将字符串分割成单词列表 s = set() for word in words: morses_word = get_morses(word) s.add(morses_word) return len(s) # 调用 words = "GIN zen gig msg" print(solve(words)) # 输出: 2 ``` --- ###
