What is a Euler or Eulerian tour?

https://iq.opengenus.org/what-is-a-euler-or-eulerian-tour/

An Euler tour or Eulerian tour in an undirected graph is a tour/ path that traverses each edge of the graph exactly once. Graphs that have an Euler tour are called Eulerian graphs. Necessary and sufficient conditions. An undirected graph has a closed Euler tour if and only if it …

Euler Tour of Tree - GeeksforGeeks

https://www.geeksforgeeks.org/euler-tour-tree/

Jul 20, 2020 · 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. Approach: We will run DFS(Depth first search) algorithm on Tree as:

Apr 04, 2018 · Euler tour becomes ‘2-0 0-1’. There is only one edge from vertex ‘1’, so we pick it, remove it and move to vertex ‘2’. Euler tour becomes ‘2-0 0-1 1-2’ Again there is only one edge from vertex 2, so we pick it, remove it and move to vertex 3. Euler tour becomes ‘2-0 0-1 1-2 2-3’
