Find Pair with Sum

Given a list of integers and a target sum \(T\), find the first pair of numbers \(a\) and \(b\) (in the order of appearance) such that \(a + b = T\). If no such pair exists, output None.

The input is provided in standard input (stdin) where the first line contains an integer \(N\) denoting the number of elements in the list. The second line contains \(N\) space-separated integers, and the third line contains the target sum \(T\). The result should be printed to standard output (stdout). If a pair is found, print the two integers separated by a space; otherwise, print None.

inputFormat

The first line contains an integer \(N\) representing the number of elements. The second line contains \(N\) space-separated integers. The third line contains an integer \(T\), the target sum.

outputFormat

If there is a pair \((a, b)\) such that \(a + b = T\), output the two numbers separated by a space. Otherwise, output None.
