```python
n = int(input()) # 这表示有n个人
t = input().split()
totle = 0
time_wait = [] # 表示第i个人的等待时间
time = [int(i) for i in t] # 表示第i个人的接水时间time
time_hao = []
for i, times in enumerate(time):
time_hao.append((i, times))
time_hao.sort(key=lambda x:x[1])
for k in range(n):
totle = totle + time_hao[k][1]
time_wait.append(totle)
print(time_hao[k][0] + 1, end=" ")
print()
print("{:.2f}".format((sum(time_wait)-time_wait[-1])/n)) # 最后一个人等到前一个人打完水，不用再加上自己打水需要的时间了
