Input The input consists of a single integer N (1 ≤N ≤ 10^5), the number of tasks, followed by N lines representing the tasks. Each task is represented by two integers S₁ and E₁ (0 ≤ S; ≤E; S 10^9), the start and end times of the task, respectively. Output Output a single integer k, the maximum number of tasks you can complete, followed by a line with k intervals of the tasks you can complete. If there are multiple solutions with the same maximum number of tasks, print any one of them. Sample Input/Output: Sample Input 1 6 25 37 46 68 79 Sample Output 1 3 1 3 46 68 You are a busy person with lots of tasks to do. You have a schedule of tasks represented by intervals of time, where each interval represents a task that you need to complete. However, you can only work on one task at a time, and you want to complete as many tasks as possible. Given a list of N intervals of time, your task is to determine the maximum number of tasks you can complete and which tasks they are.
