我正在解决有关Leetcode的问题，尽管我的代码在运行时效果很好，并且还为多个测试用例提供了正确的答案，但Leetcode检查器不接受它，并给出了运行时错误。有人可以告诉我为什么会这样吗？

问题陈述： 编写一个函数以在字符串数组中找到最长的公共前缀字符串。

如果没有公共前缀，则返回一个空字符串“”。

代码：

class Solution:
    def longestCommonPrefix(self, strs: List[str]) -> str:
        '''
        logic: Compare each letter of the first word with corresponding letters of all subsequent words.
        '''
        for i in range(len(strs[0])):
            char = strs[0][i]
            for j in range(1, len(strs)):
                if char != strs[j][i]:
                    return strs[0][0:i]    # consider answer as soon as first inequality encountered 

错误：

Runtime Error Message:
IndexError: list index out of range
    for i in range(len(strs[0])):
Line 6 in longestCommonPrefix (Solution.py)
    ret = Solution().longestCommonPrefix(param_1)
Line 31 in _driver (Solution.py)
    _driver()
Line 42 in <module> (Solution.py)
Last executed input:
[]

谢谢！
