1332. Remove Palindromic Subsequences

https://leetcode.com/problems/remove-palindromic-subsequences/

Python

• 因為Subsequence不一定要在原始s內連續，所以其實只可能有三種答案：0, 1, 2
• 題目限制len(s)最小為1，所以只可能為1或2

class Solution:
    def removePalindromeSub(self, s: str) -> int:
        if s == s[::-1]:
            return 1
        return 2
