1288 - Remove Covered Intervals.
Medium

Given an array intervals where intervals[i] = [l_i, r_i] represent the interval [l_i, r_i), 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 if c <= a and b <= 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 <= l_i < r_i <= 10⁵
- All the given intervals are unique.
