Most Focused Crew

Find the crew with the most logged work minutes, preferring the crew whose sessions are closest together.

An events coordinator records completed work sessions in the order they finish. Each session names a crew and its number of work minutes. Add the work minutes for each crew. Return the crew with the largest total number of work minutes. If crews tie for the largest total: - Return the crew whose first and final sessions are closest together in the session list. - If those spans are also tied, return the crew name that comes first alphabetically.
