To efficiently determine if any two objects in an array of DateTime intervals collide, sort the objects by their Start times. Then, iterate through the sorted array, checking pairs of intervals. If the Start time of the next object is less than the End time of the current object, a collision exists. This method leverages sorting (O(n log n)) which is effective given the constraints, allowing a quick linear scan to detect overlaps (O(n)).
To check if any two objects overlap in time, it's efficient to first sort the array based on the Start times and then check for overlaps in a single pass.
An efficient approach involves sorting the events and then checking each adjacent pair; if the Start time of the next event is less than the End time of the current, there's an overlap.
