You are given an array of events
where events[i] = [startDay_{i}, endDay_{i}]
. Every event i
starts at startDay_{i}
and ends at endDay_{i}
.
You can attend an event i
at any day d
where startTime_{i} <= d <= endTime_{i}
. You can only attend one event at any time d
.
Return the maximum number of events you can attend.
Example 1:
1 [x _]
2 [x _]
3 [x _]
Day 1 2 3 4
Input: events = [[1,2],[2,3],[3,4]]
Output: 3

Attend the third event on day 3.
Example 2:
Input: events= [[1,2],[2,3],[3,4],[1,2]]
Output: 4
Constraints:
1 <= events.length <= 10^{5}
events[i].length == 2
1 <= startDay_{i} <= endDay_{i} <= 10^{5}
