Total T-Shirts Required

You are organizing a team event where each group of participants will receive a t-shirt. Given the number of participants in each group, your task is to determine the total number of t-shirts needed.

The total number of t-shirts required is calculated using the formula: \(T = \sum_{i=1}^{n} a_i\), where \(a_i\) denotes the number of participants in the \(i^{th}\) group and \(n\) is the total number of groups.

inputFormat

The input is read from standard input (stdin) and has the following format:

• The first line contains an integer \(n\) representing the number of groups.
• The second line contains \(n\) space-separated integers where each integer \(a_i\) represents the number of participants in the \(i^{th}\) group.

If \(n=0\), then no further numbers will be provided.

outputFormat

Output a single integer to standard output (stdout) representing the total number of t-shirts required. This is the sum of all the integers provided for each group.
