各位版上的高手你们好,目前我是刚接触python的新手,
在刷leetcode 14. Longest Common Prefix 的时候,中途遇到了一个问题,
虽然距离解开答案还有一段路,现在遇到的错误如下,有尝试在colab先自行编译过,
但还是没有太大的进展而卡关,主要是想找到原因,而非直接抄答案:
Line 4: TypeError: 'type' object is not subscriptable
class Solution:
def longestCommonPrefix(self, strs: List[str]) -> str:
temp = ""
for i in list(range(len(str[0]))):
if str[0][i] == str[1][i] and str[2][i] and i <= len(str[0])-1:
temp += str[0][i]
i = i+1
else:
temp = ""
return(temp)
谢谢各位。
=================题目如下==================
Write a function to find the longest common prefix string amongst an array of
strings.
If there is no common prefix, return an empty string "".
Example 1:
Input: ["flower","flow","flight"]
Output: "fl"
Example 2:
Input: ["dog","racecar","car"]
Output: ""
Explanation: There is no common prefix among the input strings.
Note:
All given inputs are in lowercase letters a-z
================题目终点===================
