Problem

1. You can compute the factorial function either with a loop, using the definition that n! = 1 × 2 × . . . × n, or recursively, using the definition that 0! = 1 and n! = (n - 1)! × n. Is the recursive approach inefficient in this case?

2. To compute the sum of the values in an array, you can split the array in the middle, recursively compute the sums of the halves, and add the results. Compare the performance of this algorithm with that of a loop that adds the values.
