If there is a connected graph, which has a walk that passes through each and every edge of the graph only once, then that type of walk will be known as the Euler walk. Note: If more than two vertices of the graph contain the odd degree, then that type of graph will be known as the Euler Path. Examples of Euler path:Apr 27, 2023 · The first step will be to decompose the tree into a flat linear array. To do this we can apply the Euler walk. The Euler walk will give the pre-order traversal of the graph. So we will perform a Euler Walk on the tree and store the nodes in an array as we visit them. This process reduces the tree data-structure to a simple linear array. An Euler path is a walk where we must visit each edge only once, but we can revisit vertices.
