In "Table 1.15. Time Complexity of Addition", interval set/separate interval set/split interval set/interval map/split interval map += interval_sets/interval_maps 's time complexity is O(m log(n+m)), but this time complexity should be at least interval set/separate interval set/split interval set/interval map/split interval map += T::segment_type 's time complexity (O(n)). Example: the interval_sets/interval_maps contains only one big interval (whose type is T::segment_type), and this interval makes interval set/separate interval set/split interval set/interval map/split interval map += T::segment_type 's time complexity O(n).
