Conference Room Allocation

You are responsible for scheduling sessions for a conference. Each session has a start time and end time. Given a list of sessions, your task is to determine the maximum number of sessions that can be accommodated in the conference rooms, given that sessions cannot overlap. Input format: - The first line contains an integer N (1 <= N <= 1000), the number of sessions. - The next N lines contain two integers each, start and end time (0 <= start < end <= 24). Output format: - A single integer representing the maximum number of non-overlapping sessions. Example: Input: 3 1 3 2 4 3 5 Output: 2
