Find Pair with Sum

Given a list of integers and a target integer, your task is to determine whether there exists a pair of distinct numbers in the list that add up to the target. In mathematical terms, you need to find two numbers \(a\) and \(b\) such that \(a + b = \text{target}\). If such a pair exists, output the two numbers (order does not matter) separated by a single space. Otherwise, print "No pair found".

Note: The program should read input from standard input (stdin) and produce output to standard output (stdout).

inputFormat

The input consists of three lines:

1. The first line contains an integer \(n\) representing the number of elements in the list.
2. The second line contains \(n\) space-separated integers.
3. The third line contains an integer representing the target sum.

Example input:

5
1 2 3 4 5
6

If a valid pair exists, output the two integers separated by a single space. Otherwise, output "No pair found".
