So at each node of the segment tree, we have 3 informations, best sum, prefix_sum and suffix_sum. Best sum is the answer for that range [l,k]. Why do we need the prefix sum and suffix sum? If the answer lies both in my left and right half, then i'd need the best possible ...
I tried to code solution for the Segment With Maximum Sum problem from the Segment Trees Section in ITMO pilot course. Link To the Question class Sgtree{ private: vl seg,pref,suff,sum; int _n; void leaf_update(ll node,ll val) { pref[node] = val; suff[node] = val; seg[node] =...

Binary Tree Maximum Path Sum 动态规划+深度优先搜索。把大问题(求整棵树的路径最大值)拆分成小问题(每颗子树的路径最大值),递推公式为:当前树的路径最大值=max(左子树的路径最大值, 右子树的路径最大值)+当前根节点的值。以此来推出最后全树的最大路径值。

Given an unsorted array, find the maximum difference between the successive elements in its sorted form. Try to solve it in linear time/space. Return 0 if the array contains less than 2 elements. You may assume all elements in the array are non-negative integers and fit in the 32-bit si...
, a theoretical approach revealed the existence of a maximum stress of{\sigma }_{E}^{{Fracture}}that a primary C-C bond can withstand before dissociation of the covalent bond. This was obtained by comparison of the C-C bond energy and the resulting strain energy on a Kuhn segment23....
A method and apparatus are provided for routing a packet within a plurality of n nodes arranged in a line or tree (or a combination of the foregoing), given a maximum stack depth, s. A fixed stack process for routing packets on a line given a stack depth, s, initially divides a line...
