<p>You are given an integer <code>eventTime</code> denoting the duration of an event, where the event occurs from time <code>t = 0</code> to time <code>t = eventTime</code>.</p>
|
|
|
|
<p>You are also given two integer arrays <code>startTime</code> and <code>endTime</code>, each of length <code>n</code>. These represent the start and end time of <code>n</code> <strong>non-overlapping</strong> meetings, where the <code>i<sup>th</sup></code> meeting occurs during the time <code>[startTime[i], endTime[i]]</code>.</p>
|
|
|
|
<p>You can reschedule <strong>at most</strong> <code>k</code> meetings by moving their start time while maintaining the <strong>same duration</strong>, to <strong>maximize</strong> the <strong>longest</strong> <em>continuous period of free time</em> during the event.</p>
|
|
|
|
<p>The <strong>relative</strong> order of all the meetings should stay the<em> same</em> and they should remain non-overlapping.</p>
|
|
|
|
<p>Return the <strong>maximum</strong> amount of free time possible after rearranging the meetings.</p>
|
|
|
|
<p><strong>Note</strong> that the meetings can <strong>not</strong> be rescheduled to a time outside the event.</p>
