Total Books Read in the Book Club

In the book club, each child reads a certain number of books during the month. You are given the number of children, N, and a list of N integers where the i-th integer represents the number of books read by the i-th child. Your task is to compute the total number of books read by the entire club.

Mathematically, if each child i reads (b_i) books, then the total number of books is given by (\sum_{i=1}^{N} b_i).
