Minimum Total Booths

In a book fair, each bookseller requires a certain number of booths. Given an integer n representing the number of booksellers and an array of n integers where each integer indicates the number of booths required by a bookseller, your task is to determine the minimum total number of booths needed.

Mathematically, if the booths required by the booksellers are given as an array \( A = [a_1, a_2, \dots, a_n] \), you need to compute the sum:

\( \sum_{i=1}^{n} a_i \)

inputFormat

The input is given via standard input in the following format:

n
b1 b2 ... bn

Where:

• n is the number of booksellers.
• b1, b2, ..., bn are the number of booths required by each bookseller.

outputFormat

Output a single integer via standard output representing the minimum total number of booths used by summing the booths required for each bookseller.
