(80 points) Run-time analysis In this part of the assignment, you are going to implement two algorithms for determining whether a number is a sum of two numbers in a given list of integer numbers. This is the problem from HW1. For simplicity, we allow a number to be used twice in forming the sum. For example, if the target is 20, and the list contains the number 10, then 20 = 10 + 10 and thus 20 is considered to a sum of two numbers from the list. You need to implement two algorithms: Brute-force: You simply try all possible pairs of numbers to see if a given number matches each sum. Binary-search: You would first sort the list of numbers and then perform binary search on the numbers. You can use built-in sorting function. If you write sorting yourself, make sure to write an efficient sorting algorithm (O(nlogn) time). Now implement both algorithms using your favorite language (perhaps Python). Then run your program on the provided data to compare how the two different algorithms perform on small to large data files. Here are more detailed instructions: You have two sets of files: 1. files listNumbers-n (listNumbers-10, listNumbers-100, listNumbers-1000, listNumbers-10000, listNumbers-100000, listNumbers-1000000) each one of these files contain different data size 10, 100, 1000, 10000, 100000, 1000000 random numbers respectively. 2. files listNumbers-n-nsol, each one of these files contain 10 numbers. What you need to do: 1. For each number x in listNumbers-n-nsol file: 2. look for two numbers in listNumbers-n file, where the sum of these two numbers = x, or one number if you use it twice will also sum to x (ex: x = 30, and you found 15 in listNumbers-n list) 3. repeat that for all pair of files (listNumbers-n and listNumbers-n-nsol) Note: you don't need to find all pairs that sum to x, if you found one, then stop and proceed to the next number in list listNumbers-n-nsol File listNumbers-10-wsol is an example of that.
