Learn more about mathematics, euler path/circuit.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.The problem becomes more interesting when only using basic R code. I developed the big.add function to solve Euler Problem 13 through the addition of very large integers. We can extend this function to also calculate factorials. A factorial can be replaced by a series of additions, for example: $$3! = 1 \times 2 \times 3 = (((1+1) + (1+1)) + (1 ...is a closed walk containing all of those edges. The degreeof the face is the minimum length of a boundary walk. For example, in the figure below, the lefthand graphhas three faces.

The noble and the rich could travel in some comfort!in private, and in upholstered carriages accompanied by footmen …The Criterion for Euler Paths Suppose that a graph has an Euler path P. For every vertex v other than the starting and ending vertices, the path P enters v thesamenumber of times that itleaves v (say s times). Therefore, there are 2s edges having v as an endpoint. Therefore, all vertices other than the two endpoints of P must be even vertices. Walk-in tubs are becoming increasingly popular for seniors who want to maintain their independence and safety while bathing.
