// Ncontracts Code Challenge
//
//
// Please take a look at the code below.
// Even though the program runs and generates correct result, we consider the code to be bad.
// For example, if we want to expand the Christmas discount to January or if we want to introduce a first responder discount, the code can get really messy.
// We ask you to refactor the code so that it's easier to apply new changes to it.
// Once done, please send me a link to your gists.
