✅ Help with an Algorithm on time intervals

var result = new Dictionary<(TimeOnly, TimeOnly), int>();
var intervals = Availables.Values.OrderBy(interval => interval.Item1).ToList(); //sort by start time
var interval = intervals.First();
var availableMembers = 1;
for (var i = 1; i < Availables.Count; i++)
{
    var currentInterval = intervals[i];
    var currentStart = currentInterval.Item1;
    var currentEnd = currentInterval.Item2;
    var previousInterval = intervals[i - 1];
    var previousEnd = previousInterval.Item2;
    if (currentStart > previousEnd) //no overlap
    {
        result.Add(interval, availableMembers);
        availableMembers = 1;
        continue;
    }
    availableMembers++;
    var minEnd = currentEnd < previousEnd ? currentEnd : previousEnd;
    interval = (currentStart, minEnd);
}
return result;
