在程式碼前，要注意60屬於及格，測資中有一個就是抓60這個
num = int(input())
low = 0
high = 0
score = list(map(int,input().split()))
score.sort()
for i in range(num):
if i != num-1:
print(score[i], end=' ')
else:
print(score[i])
for j in range(num):
if score[num-j-1] < 60:
print(score[num-j-1])
low = 1
break
if low == 0:
print("best case")
for k in range(num):
if score[k] >= 60:
print(score[k])
high = 1
break
if high == 0:
print("worst case")
