1288 - Remove Covered Intervals.Medium
Given an array
intervals
whereintervals[i] = [li, ri]
represent the interval[li, ri)
, remove all intervals that are covered by another interval in the list.The interval
[a, b)
is covered by the interval[c, d)
if and only ifc <= a
andb <= d
.Return the number of remaining intervals.
Example 1:
Input: intervals = [[1,4],[3,6],[2,8]]
Output: 2
Explanation: Interval [3,6] is covered by [2,8], therefore it is removed.
Example 2:
Input: intervals = [[1,4],[2,3]]
Output: 1
Constraints:
1 <= intervals.length <= 1000
intervals[i].length == 2
0 <= li < ri <= 105
- All the given intervals are unique.
