    56 - Merge Intervals\.

    Medium

    Given an array of intervals where <code>intervalsi = start<sub>i</sub>, end<sub>i</sub></code>, merge all overlapping intervals, and return an array of the non-overlapping intervals that cover all the intervals in the input.

    Example 1:

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

    Output: [1,6,8,10,15,18]

    Explanation: Since intervals 1,3 and 2,6 overlap, merge them into 1,6.

    Example 2:

    Input: intervals = \[\[1,4],4,5]

    Output: [1,5]

    Explanation: Intervals 1,4 and 4,5 are considered overlapping.

    Constraints:

    • <code>1 <= intervals.length <= 10<sup>4</sup></code>

    • intervals[i].length == 2

    • <code>0 <= start<sub>i</sub><= end<sub>i</sub><= 10<sup>4</sup></code>
