Write and Test a Function

EasyPython

Problem

Turing Mobile receives availability windows during which a mobile workflow may run. Given a collection of time intervals, merge every overlapping or adjacent interval so the result contains the fewest possible non-overlapping windows.

Formal Specification

Implement merge_mobile_windows(windows), where windows is a list of intervals. Each interval is represented as a two-element list [start, end], with integer time values and start <= end. Return a new list of merged intervals sorted by start. Intervals that overlap or touch, such as [1, 3] and [3, 5], must be merged into [1, 5]. Do not mutate the input list.

Constraints

  • 0 <= len(windows) <= 10^4
  • Each interval contains exactly two integers
  • -10^9 <= start <= end <= 10^9
  • Intervals that touch must be merged
  • The input list must not be mutated
