Merge Intervals

20:00

Medium

Given one interval per line as start end, merge overlaps and print merged intervals as start end groups joined by |.

Example 1

Input: intervals = [[1,3],[2,6],[8,10],[15,18]]

Output: 1 6|8 10|15 18

[1,3] and [2,6] overlap.

Constraints

0 <= interval count <= 10^4start <= end for every interval

Recall before you code

Capture your plan, then rate how clearly you recalled it before submitting.
