💡 풀이법

- Python

from collections import deque
def solution(progresses, speeds):
    answer = []
    progresses, speeds = deque(progresses),deque(speeds)

    while progresses:
        n = 0
        for i in range(len(progresses)):  
            progresses[i] += speeds[i]
        
        while progresses and progresses[0] >= 100:
            progresses.popleft()
            speeds.popleft()
            n += 1
        
        if n != 0:
            answer.append(n)

    return answer

 

- Java

            p.offer(progresses[i]);
            s.offer(speeds[i]);
        }

        int n = 1;
        while (p.size() > 0) {

        }
        int[] answer = new int[ans.size()];

        for (int i = 0; i < ans.size(); i++) {
            answer[i] = ans.get(i);
        }
