약간(?)의 시간 초과가 있었지만 통과함. (1번 시도 실패, 2번 시도 성공)
그냥 정말 별생각 없이 짠 코드였음;
class Solution:
def isPalindrom(self, s: str) -> bool:
for i in range(len(s)//2):
if s[i] != s[-(i+1)]:
return False
return True
def countSubstrings(self, s: str) -> int:
l = len(s)
res = l
for i in range(l):
for j in range(i+1, l):
res += 1 if self.isPalindrom(s[i:j+1]) else 0
return res
