    3169 - Count Days Without Meetings\.

    Medium

    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.

    Example 1:

    Input: days = 10, meetings = \[\[5,7],1,3,9,10]

    Output: 2

    Explanation:

    There is no meeting scheduled on the 4<sup>th</sup> and 8<sup>th</sup> days.

    Example 2:

    Input: days = 5, meetings = \[\[2,4],1,3]

    Output: 1

    Explanation:

    There is no meeting scheduled on the 5<sup>th</sup> day.

    Example 3:

    Input: days = 6, meetings = \[\[1,6]]

    Output: 0

    Explanation:

    Meetings are scheduled for all working days.

    Constraints:

    • <code>1 <= days <= 10<sup>9</sup></code>

    • <code>1 <= meetings.length <= 10<sup>5</sup></code>

    • meetings[i].length == 2

    • 1 &lt;= meetings[i][0] &lt;= meetings[i][1] &lt;= days
