Product of a List

You are given a list of integers. Your task is to compute the product of all elements in the list.

Note: If the list is empty, the product is defined as 1.

For example, given the list [1, 2, 3, 4], the product is 24.

This problem requires you to read input from standard input and output the result to standard output.

inputFormat

The first line contains a single integer n which represents the number of elements in the list. If n > 0, the second line contains n space-separated integers.

If n is 0, then the list is considered empty.

outputFormat

Output a single integer representing the product of all integers in the list.
