Re-implement your function from Part V of the assignment, this time using only recursion and no loops. The recursive function is to be called recursive_num_of_pushups(). The function takes the same arguments (cur_push_ups and days) and increases the number of push-ups each day according to the same scheme. The general structure of the function will be a multi-way if-statement with function calls to recursive_num_of_pushups(). Naturally, with each recursive call, the argument day must be decremented (decreased by 1). The base case that terminates the recursion is reached when days equals 1.
