The interviewer asked me to give my introduction.

He asked about my projects on my resume.

That was followed by questions about my hobbies and interests.

Then he asked a coding question, followed by him asking me to code the solution.

Given a set of time intervals in any order, our task is to merge all overlapping intervals into one and output the result, which should have only mutually exclusive intervals.

Input: Intervals = {{1,3},{2,4},{6,8},{9,10}} Output: {{1, 4}, {6, 8}, {9, 10}} Explanation: Given intervals: [1,3],[2,4],[6,8],[9,10], we have only two overlapping intervals here, [1,3] and [2,4]. Therefore, we will merge these two and return [1,4], [6,8], [9,10].

Input: Intervals = {{6,8},{1,9},{2,4},{4,7}} Output: {{1, 9}}
