You are a consultant for a construction company. They are able to order fence segments in large 5 foot pieces, and short 1 foot pieces. However, they often realize after trying to build a fence of length L that they are unable to do so. Given the number of large fence pieces N, the number of small pieces n, and the desired length of fence L, write a function that returns True if the fence can be made and False if the fence cannot be made.
