코딩테스트 연습 - 다음 큰 숫자

 

Solution

def solution(n):
    answer = 0

    n2 = bin(n)[2:]

    count_n = n2.count('1')

    while True:
        n += 1
        t = bin(n)[2:]

        count_t = t.count('1')

        if count_t == count_n:
            return n

🔑 key point: if count_t == count_n: return n

 

Other Solution

def solution(n):
    cnt1 = bin(n).count('1')

    for bi in range(n + 1, 1000001):
        if bin(bi).count('1') == cnt1:
            answer = bi
            return answer

🔑 key point: if bin(bi).count('1') == cnt1: answer = bi; return answer
