   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

   3 godz. 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.

   Contribution Technique on Trees. Watch the video for a high level overview before reading the blog. You are given a rooted tree. How do you find out the distance between any 2 nodes? Denote $d[u]$ to be the distance of node $u$ from the root. It can be calculated with simple Tree DP while doing a DFS on the tree.
