class Solution:

def longestCommonPrefix(self, strs: List[str]) -> str:

i=0

prefix = ""

size = len(strs)

if size ==0:

return ""

if size ==1:

return strs[0]

strs.sort()

while i < len(strs)-1 and strs[i][i] == strs[i+1][i]:

prefix +=strs[i][i]

i+=1

return prefix

Leet code is giving me an error:

IndexError: string index out of range while i < len(strs)-1 and strs[i][i] == strs[i+1][i]: Line 11 in longestCommonPrefix (Solution.py) ret = Solution().longestCommonPrefix(param_1) Line 35 in _driver (Solution.py) _driver() Line 46 in (Solution.py)
