백준 시험 감독(13458번 문제) Python3 코드

코드 1) -> 시간초과

import math
import sys

exam_room = int(sys.stdin.readline().strip())

student_str = sys.stdin.readline().strip()
student_list = []
if " " in student_str:
  student_list = list(map(int, student_str.split(" ")))
else:
  student_list.append(int(student_str))

main, sub = map(int, input().split(" "))

need_pd = 0
for student in student_list:
  need_pd += 1
  student -= main

  while student > 0:
    need_pd += 1
    student -= sub

print(need_pd)

코드 2) -> 틀렸습니다

import math
import sys

exam_room = int(sys.stdin.readline().strip())

student_str = sys.stdin.readline().strip()
student_list = []
if " " in student_str:
  student_list = list(map(int, student_str.split(" ")))
else:
  student_list.append(int(student_str))

main, sub = map(int, input().split(" "))

need_pd = 0
for student in student_list:
  need_pd += 1
  student -= main

  if student <= 0:
    break

  need_pd += math.ceil(student / sub)

print(need_pd)
