WebLi chao tree This is a data structure used to maintain the relationship between line segments on a plane (Cartesian coordinate system). Li chao line segment tree … WebThe answer is the maximum distance from the node containing. ( 1, 1) (1, 1) (1,1) to another node. We can use BFS to find this distance. For a detailed proof of why this works, see the official editorial. Although this gives us an \mathcal O (NM) O(NM) solution, there is a simpler solution using 0/1 BFS! how many european flags can you nameWebLi Chao Tree works for functions that intersect only in one point. Constraints of the problem were such that there would always be at most on intersecting point between to functions with x>=350.
