❔ Which of these two "best-fit" algorithms are better?

 private static List<int> FindOptimalUnits(LocalDate requestedStartDate, LocalDate requestedEndDate, int requestedQty, Dictionary<int, IPeriod[]> units)
        {
            var accommodationGapSize = new Dictionary<int, int>();


            foreach (var unit in units)
            {
                var currentClosestEndDate = LocalDate.MinIsoValue;
                var currentClosestStartDate = LocalDate.MaxIsoValue;

                foreach (var period in unit.Value)
                {
                    if (period.EndDate <= requestedStartDate && period.EndDate > currentClosestEndDate)
                    {
                        currentClosestEndDate = period.EndDate;
                    }

                    if (period.StartDate >= requestedEndDate && period.StartDate < currentClosestStartDate)
                    {
                        currentClosestStartDate = period.StartDate;
                    }

                    if (currentClosestEndDate == requestedStartDate && currentClosestStartDate == requestedEndDate)
                    {
                        break; // Cannot find a better 
                    }
                }

                var gapSize = Period.Between(currentClosestEndDate, currentClosestStartDate, PeriodUnits.Days).Days;
                accommodationGapSize.Add(unit.Key, gapSize);

            }


            foreach (var item in accommodationGapSize)
            {
                Console.WriteLine(item.Value);
            }
            return accommodationGapSize.OrderBy(x => x.Value).Take(requestedQty).Select(x => x.Key).ToList();
        }
    }
