You are given a positive integer days representing the total number of days an employee is available for work (starting from day 1). You are also given a 2D array meetings of size n where, meetings[i] = [start_i, end_i] represents the starting and ending days of meeting i (inclusive).
Return the count of days when the employee is available for work but no meetings are scheduled.
Note: The meetings may overlap.
Examples
Example 1
Input: days = 10, meetings = [[5,7],[1,3],[9,10]]
Output: 2
Explanation:
There is no meeting scheduled on the 4 th and 8 th days.
Example 2
Input: days = 5, meetings = [[2,4],[1,3]]
Output: 1
Explanation:
There is no meeting scheduled on the 5 th day.
Example 3
Input: days = 6, meetings = [[1,6]]
Output: 0
Explanation:
Meetings are scheduled for all working days.
Constraints
1 <= days <= 109
1 <= meetings.length <= 105
meetings[i].length == 2
1 <= meetings[i][0] <= meetings[i][1] <= days
