처음엔 뭔 문제여.. 했는데 그냥 리스트로 구현하면 되는 거였음.

다른 사람의 풀이를 보니 @staticmethod 어노테이션 써서 구현하는 거 같긴 한데.. 크게 차이는 없을 듯?

class Solution:
    def backspaceCompare(self, s: str, t: str) -> bool:
        ss, tt = [], []
        
        for i in range(len(s)):
            if s[i] != '#':
                ss.append(s[i])
                continue
            if ss:
                ss.pop()            
        
        for i in range(len(t)):
            if t[i] != '#':
                tt.append(t[i])
                continue
            if tt:
                tt.pop()
                
        return ss == tt
