You are given a list of randomly arranged numbers, for example (11,7,18,5,17,13). The triple (11,7, 5) is called the "inversion triple" because (5<7<11) in terms of value, while the index of 5 in the list is greater than the index of 7, and the index of 7 is greater than 11. Therefore, we can find 2 inversions in such list as follows: (11,7,5), and (18,17,13). Your main task is to find the total number of inversions in any given list. a) Design a brute-force algorithm to return the number of possible inversions, and analyse the complexity of your solution b) Develop a python code to implement your brute-force algorithm. [The marks depend on the correctness of the code, indentation, comments, test-case] c) Design a more efficient algorithm to do the same task with less complexity, and analyse the complexity of your solution.

What are the properties of sets, lists, vectors, strings and are they mutable or immutable? What type of problems is each one best used for over the other type? E.g if I have a function that solves a problem using a list, why wouldn't I be able to use a vector or set for it? Can I have some code that shows this in Racket?

Consider a situation of a boarding gate of a plane where passengers are allowed to board on the place based on their age. All passengers are on a line (queue) to board on the place, however, the oldest one is always allowed to board first no matter when he/she got in the line (queue). In this case, you cannot sort the passengers by their age, however, you know that oldest ones are always at the top of the line. This is an example of a priority queue where data will be accessed and processed based on their level of priority. Suppose you need to organize such type of data so that the data in highest priority can be accessed in a constant time, O(1). What type of data structure would you use in such cases? Justify your answer.
