各位版上的高手你們好,目前我是剛接觸python的新手,
在刷leetcode 14. Longest Common Prefix 的時候,中途遇到了一個問題,
雖然距離解開答案還有一段路,現在遇到的錯誤如下,有嘗試在colab先自行編譯過,
但還是沒有太大的進展而卡關,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)
謝謝各位。
=================題目如下==================
Write a function to find the longest common prefix string amongst an array of

Output: "fl"
Example 2:
Input: ["dog","racecar","car"]
