A car showroom consists of N numbered spaces. Each space can hold at most one car. The spaces are indexed starting from 0 though the last space, N - 1. No two cars in the showroom are the same model. Write the CarShowroom method findCarSpace. This method returns the index of the space in which the car with the specified model is located. If there is no car of that model in the showroom, the method returns -1. Then write the CarShowroom method consolidate. This method should move the cars so that cars in adjacent spaces, starting at index 0, have no empty spaces between any two cars. Keep the order of the cars the same as the array in the code shows.
