436 - Find Right Interval.Medium
You are given an array of
intervals
, whereintervals[i] = [starti, endi]
and eachstarti
is unique.The right interval for an interval
i
is an intervalj
such thatstartj
>= endi
andstartj
is minimized.Return an array of right interval indices for each interval
i
. If no right interval exists for intervali
, then put-1
at indexi
.Example 1:
Input: intervals = [[1,2]]
Output: [-1]
Explanation: There is only one interval in the collection, so it outputs -1.
Example 2:
Input: intervals = [[3,4],[2,3],[1,2]]
Output: [-1,0,1]
Explanation:
There is no right interval for [3,4].
The right interval for [2,3] is [3,4] since start0 = 3 is the smallest start that is >= end1 = 3.
The right interval for [1,2] is [2,3] since start1 = 2 is the smallest start that is >= end2 = 2.
Example 3:
Input: intervals = [[1,4],[2,3],[3,4]]
Output: [-1,2,-1]
Explanation:
There is no right interval for [1,4] and [3,4].
The right interval for [2,3] is [3,4] since start2 = 3 is the smallest start that is >= end1 = 3.
Constraints:
1 <= intervals.length <= 2 * 104
intervals[i].length == 2
-106 <= starti <= endi <= 106
- The start point of each interval is unique.
