Problem Statement  
Next month you are going to a conference about new trends in programming. It is time to choose a hotel in which you will stay for this time. There are several hotels in a city, all available for you. You are given a int[] price, where the ith element is the price of the ith hotel. Similarly, you are given a int[] quality, where the ith element is the quality of the ith hotel. Lower prices are better, and higher quality values are better. We say that hotel X is disadvantageous if there is a hotel Y whose price and quality are both at least as good as hotel X, and whose price or quality (or both) is strictly better than hotel X. Return the number of disadvantageous hotels in the city.
