Euler Tour of Tree - GeeksforGeeks

Mar 30, 2018 · Euler tour is defined as a way of traversing tree such that each vertex is added to the tour when we visit it (either moving down from parent vertex or returning from child vertex). We start from root and reach back to root after visiting all vertices. It requires exactly 2*N-1 vertices to store Euler tour.2/5

EULER TOUR TECHNIQUE An Euler circuit of a graph is an edge-disjoint circuit which traverses all the nodes. A graph permits an Euler circuit if and only if each vertex has equal indegree and outdegree. An Euler circuit can be used for optimal parallel computation of many tree functions.

Euler Tour Subtree Sum using Segment Tree - GeeksforGeeks

Apr 17, 2018 · Euler tour tree (ETT) is a method for representing a rooted tree as a number sequence. When traversing the tree using Depth for search (DFS), insert each node in a vector twice, once while entered it and next after visiting all its children. This method is very useful for solving subtree problems and one such problem is Subtree Sum.3.3/5

Euler Tour Technique We have already seen this in the pointer jumping lecture. Application to problem 2: preorder tree traversal. Euler tour of the tree. Euler tour of the tree. Euler tour of the tree. If all vertices are of even degrees, it’s an Euler graph. Special data structure for tree, finding successors.

Euler Tour of a tree is defined as the path traversed in the graph such that each vertex is added to the path as it is visited. This includes both entering from parent to child and child to parent traversal. The tour starts from the root and ends at the root after traversing all the nodes. Let’s see an example.
