► Problem açıklaması:

Given a list of intervals, remove all intervals that are covered by another interval in the list.

Interval [a,b) is covered by interval [c,d) if and only if c lessEqual a and b lessEqual d.

After doing so, 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

Example 3:

Input: intervals = [[0,10],[5,12]]

Output: 2

Example 4:

Input: intervals = [[3,10],[4,10],[5,11]]

Output: 2

Example 5:

Input: intervals = [[1,2],[1,4],[3,4]]

Output: 1

Constraints: All the intervals are unique.
