Write a method that returns the total number of nodes, including the root node, in a "web structure". A web structure is created by starting at a root node, then branching out into 'splitsPerNode' multiple first-layer nodes. For each of those first-layer nodes you then branch out into 'splitsPerNode' second-layer nodes. Your method returns the total number of nodes in the structure where 'splitsPerNode' is how many branches there are from each node at each layer and 'layers' is the total number of layers. If layers=0 the structure only has the root node and you should return 1. Please look at the test data for examples. Also, please ask your teacher to diagram a few examples on the board for clarity.
