interval-tree

问题 This is an algorithmic question about a somewhat complex problem. The foundation is this: A scheduling system based on available slots and reserved slots . Slots have certain criteria, let's call them tags . A reservation is matched to an available slot by those tags, if the available slot's tag set is a superset of the reserved slot. As a concrete example, take this scenario: 11:00 12:00 13:00 +--------+ | A, B | +--------+ +--------+ | C, D | +--------+ Between the times of 11:00 to 12:30

问题 I have aset of ip ranges and i need to find if the ip given by the user exists between the given list of ip ranges . This is in continuation to this question How to check if a given ip falls between a given ip range using node js Jonas helped me get the ip exists or not. But i donot want to do a exhaustive iterative search , I want to go a fast performance intensive search as my list of ip ranges (or number ranges) will be huge. I looked into bloom filters as pointed by jonas but i am not

问题 Given a list of intervals of time, I need to find the set of maximum non-overlapping intervals. For example, if we have the following intervals: [0600, 0830], [0800, 0900], [0900, 1100], [0900, 1130], [1030, 1400], [1230, 1400] Also it is given that time have to be in the range [0000, 2400] . The maximum non-overlapping set of intervals is [0600, 0830], [0900, 1130], [1230, 1400] . I understand that maximum set packing is NP-Complete. I want to confirm if my problem (with intervals containing

问题 What are differences between segment trees, interval trees, binary indexed trees and range trees in terms of: Key idea/definition Applications Performance/order in higher dimensions/space consumption Please do not just give definitions. 回答1: All these data structures are used for solving different problems: Segment tree stores intervals, and optimized for " which of these intervals contains a given point " queries. Interval tree stores intervals as well, but optimized for " which of these

问题 I am implementing red-black tree deletion for interval trees following CLRS 2nd edition, fourth printing, pg 288-9. Summary of bug: RB-Delete-Fixup If x and w are the sentinel nodes, which is a possible consequence of RB-Delete, then the evaluation of color(left(w)) resp. color(right(w)) in RB-Delete-Fixup suffers a null pointer exception on the first iteration of the while loop. (if (and (= (get-color (get-left @w)) black) (= (get-color (get-right @w)) black)) ;; Bug here! All of the code

问题 You are given two lists of intervals, A and B . In A , the intervals are sorted by their starting points. None of the intervals within A overlap. Likewise, in B , the intervals are sorted by their starting points. None of the intervals within B overlap. Return the intervals that overlap between the two lists. Example: A: {[0,4], [7,12]} B: {[1,3], [5,8], [9,11]} Return: {[1,3], [7,8], [9,11]} I got this in an interview and was stumped. I thought of comparing intervals between the two lists.

问题 I have a list of intervals with integer values [eg. [1, 4], [10, 19] etc.]. Is there a way to put these intervals into some java collections' container [eg. Set] such that I can call a 'union' function on the container. The 'union' function should give me a list of intervals such that if any 2 inserted intervals overlap then they should be merged in the output. I tried using the Range class in Guava but ended up comparing all the intervals against each other before merging. An elegant
