Merge Overlapping Trade Intervals | Dataford Interview Questions

At a trading firm like Jane Street, market activity is recorded as time intervals. Given a list of intervals representing active trading windows, merge all overlapping intervals and return the condensed list in ascending order.

Formal Specification

Implement a function that takes intervals, a list of lists where each element is [start, end] and start <= end. Return a new list of merged intervals, where any overlapping or touching intervals are combined into a single interval.

Constraints

1 <= len(intervals) <= 10^4
intervals[i].length == 2
0 <= intervals[i][0] <= intervals[i][1] <= 10^6
Intervals may be unsorted
Touching intervals should also be merged

Function Signature
