heapq 를 사용하면 쉽게 해결가능하다.

 

import heapq
def solution(scoville, K):
    answer = 0
    heapq.heapify(scoville)
    while scoville:
        if scoville[0] < K:
            answer += 1
            if len(scoville)==1: return -1
            heapq.heappush(scoville, heapq.heappop(scoville) + heapq.heappop(scoville)*2)
        else:
             return answer
