# 方式1：使用input接收输入
while True:
    try:
        n = input()
        nums = []
        for i in range(int(n)):
            nums.append(int(input()))
        nums = list(set(nums))
        nums = sorted(nums)
        for num in nums:
            print(num)
    except:
        break


# 方式2：使用sys.stdin接收输入
# import sys

# args = []
# for line in sys.stdin:
#     a = line.strip()
#     args.append(int(a))

# n, nums = args[0], args[1:]

# nums = list(set(nums))
# nums.sort()
# for num in nums:
#     print(num)
