Find the Largest Number in a List

You are given a list of integers. Your task is to find the largest number in this list. If the list is empty, output None.

Mathematically, for a list \(a_1, a_2, \dots, a_n\) where \(n > 0\), you need to compute \(\max(a_1, a_2, \dots, a_n)\). If \(n = 0\), output None.

inputFormat

The input is given from standard input (stdin) and consists of two parts:

• The first line contains an integer \(n\) representing the number of elements in the list.
• If \(n > 0\), the second line contains \(n\) integers separated by spaces.

If \(n = 0\), no further input is provided.

outputFormat

Output the largest integer from the list to standard output (stdout). If the list is empty, output None (without quotes).
