WebAn Euler path is a path that uses every edge in a graph with no repeats. Being a path, it does not have to return to the starting vertex. Example In the graph shown below, there are … WebThere are a lot of examples of the Euler path, and some of them are described as follows: Example 1: In the following image, we have a graph with 4 nodes. Now we have to determine whether this graph contains an Euler path. Solution: The above graph will contain the Euler path if each edge of this graph must be visited exactly once, and the ...
