2.1 Given an unsorted std::vector<int> and a number n, what is the worst-case time complexity for finding the pair of integers whose sum is closest to n, using no additional memory? For example, given the vector {12, 3, 17, 5, 7} and n = 13, we would get the pair {5, 7}.
No one has ever found an algorithm for the Traveling Salesperson problem whose worst-case time complexity is better than exponential. Yet, no one has ever proven that such an algorithm is impossible. Select one: True False
What is the worst-case asymptotic time complexity of the following divide-andconquer algorithm (give a Θ-bound). The input is an array A of size n. You may assume that n is a power of 2. (NOTE: It doesn’t matter what the algorithm does, just analyze its complexity). Assume that the non-recursive function call, bar(A1,A2,A3,n) has cost 3n. Show your work! Next to each statement show its cost when the algorithm is executed on an imput of size n abd give the...
