Suppose you are choosing between the following three algorithms: algorithm a solves problems by dividing them into ve subproblems of half the size, recursively solving each subproblem, and then combining the solutions in linear time. algorithm b solves problems of size n by recursively solving two subproblems of size n 1 and then combining the solutions in constant time. algorithm c solves problems of size n by dividing them into nine subproblems of size n=3, recursively solving each subproblem, and then combining the solutions in o(n2) time. what are the running times of each of these algorithms (in big-o notation), and which would you choose
