Exams - The Teteven Trip

/* You will receive as input data an array of n elements. Each element will consist of a string in the format:
 * "[car model] [fuel type] [route number] [luggage weight]", separated by exactly 1 space.
 * The base fuel consumption is 10L per 100km. There are 3 fuel types - 'gas', 'petrol' and 'diesel'.
 * Each type has a correction coefficient c: for gas c = 1.2, for petrol c = 1, for diesel c = 0.8.
 * For every kg of luggage you need to add 0.01L extra fuel consumption.
 * There are 2 routes to Teteven - route '1' and route '2'. Route '1' is long 110km (100km normal road
 * and 10km snowy road). Route '2' is long 95km (65km normal road and 30km snowy road).
 * The total fuel consumption is calculated by multiplying the base fuel consumption and the total route distance.
 * Then you should add the route's snow distance multiplied by 30% of the base fuel consumption.
 * The end you should round the fuel liters to an integer value!
 * The output consist of n lines. Each line should hold the car model, the fuel type, the route number, and
 * the quantity of fuel needed in liters (all space-separated). The quantity of fuel is rounded to
 * an integer number. */
