Unique Numbers from Input

Write a program that reads an integer N from standard input followed by N integers (all separated by whitespace). Insert the N integers into a set<int> and print the distinct values in ascending order on one line, separated by single spaces, followed by a newline (a trailing space after the last value is fine).

Example input:
5
3 1 3 2 1

The output for that input is shown in Expected Output.

Expected Output:

1 2 3↵
5 10 15 20↵

= newline. The output ends with a newline — print one after the last line.
