160 intersecting linked list Given two linked lists, judge whether they intersect at a point, and find the intersection node. The input is two linked lists and the output is one node. If there are no intersecting nodes, an empty node is returned. Input: intersectVal = 8, listA = [4,1,8,4,5], listB = [5,0,1,8,4,5], skipA = 2, skipB = 3 Out ...

preface Tree chain subdivision divides the edges of the tree into many chains, so as to reduce the complexity of modifying queries on the tree. This is an introduction to light and heavy chain segmentation. Concept: Heavy son: the son with the most nodes in the subtree. If the subtrees of two sons are the same, then any one of them. Light son: ...

1, Hierarchical traversal of binary tree It is unrealistic to traverse directly, because there are more nodes in the future, and not all nodes in each layer are 2k-1. If you traverse a node, save the child of the node and get it from the structure next time. Here, the child is saved in a queue (the node first placed in the space is ...
