参考代码:

n=int(input())

a_list=list(map(int,input().split()))

a_list.sort()

count=dict()

for i in a_list:

  if i not in count:

    count[i]=1

  else:

    count[i]+=1

i=a_list[0]

while count[i]:

  if count[i]%(i+1)!=0:

    break

  else:

    if i+1 not in count:

      count[i+1]=0

    count[i+1]+=count[i]//(i+1)

    i+=1

print(i)
