The DFS tree and observation 1 are the core of Tarjan's bridge-finding algorithm. Typical tutorials about finding bridges only mention the DFS tree in passing and start by defining weird arrays
1 godzinę temu · The idea: Suppose in the input of a problem, you are given a tree as n − 1 n − 1 edges. To construct the XOR Linked Tree data-structure from this, you go through all of the edges and compute the following two things for every node in the tree: deg[node] = The degree of the node. xor[node] = The XOR of all neighbours of the node.
A directed DFS tree is an explicit representation of a DFS traversal of a directed graph. When a node is visited for the first time, it is added to the tree, either as a root if it was visited in the beginning of a DFS call, or as the child of the node it got visited from.
