Concert Seating Arrangement

You are organizing a concert with a fixed number of seats available. Each seat can accommodate one person, and attendees may prefer sitting together in groups. Given a list of groups and their sizes, you need to determine the maximum number of attendees that can be seated while respecting the groups' sizes. Input Format: - The first line contains two integers `s` (total number of seats) and `g` (number of groups). - The next `g` lines each contain an integer representing the size of each group. Output Format: - Print the maximum number of attendees that can be seated without splitting any group. Example: Input: 10 4 2 3 5 1 Output: 10
