There is a data which provides heights (in meter) of mountains. The data is only for ten mountains.  Write a program which prints heights of the top three mountains in descending order.
mt = list()
n = 10

for i in range(n):
    mt.append(int(input()))
mt.sort(reverse=True)
print(mt[0:3])
mt = list()
n = 10

for i in range(n):
    mt.append(int(input()))
mt.sort(reverse=True)
for j in range(3):
    print(mt[j])
