솔루션1)

• defaultdict() 사용해서 풀기

class Solution:
    def areOccurrencesEqual(self, s: str) -> bool:
        d = defaultdict(int)
        for c in s:
            d[c] += 1
        
        return len(set(d.values())) == 1

솔루션2)

• 리스트 원소 갯수를 세는 Counter 객체를 사용해서 풀기

class Solution:
    def areOccurrencesEqual(self, s: str) -> bool:
        counter = Counter(s)
        return len(set(counter.values())) == 1
