- What are the conditions under which a recursive algorithm will no longer call itself?arrow_forwardIn a recursive algorithm, the goal is to solve a problem by breaking it into smaller sub-problems to solve. This is accomplished by constructing an algorithm using two important components. What are these components, what is the purpose of each?arrow_forwardWhat are the advantages and disadvantages of iterative algorithms compared to recursive algorithms, and in what scenarios would you prefer to use one over the other?arrow_forward
- How much more time and memory does it take for a computer to execute a recursive function compared to a non-recursive one?arrow_forwardWhen an algorithm that normally recursively calls itself will no longer do so, what are the conditions that must be met?arrow_forwardExplain the benefits a recursive algorithm can provide. What are the negative aspects of using recursion?arrow_forward
- Recursion is the best and the fastest way to solve any problem.True or Falsearrow_forwardWhen is a recursive algorithm preferable to an iterative method?arrow_forwardRECURSIVE PYTHON The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: fibonacci(7) is 13 Note: Use recursion and DO NOT use any loops. # TODO: Write recursive fibonacci() functiondef fibonacci(): if __name__ == "__main__": start_num = int(input()) print('fibonacci({}) is {}'.format(start_num, fibonacci(start_num)))arrow_forward
- What circumstances must be satisfied for an algorithm that ordinarily recursively calls itself to no longer do so?arrow_forwardWrite the pseudocode for a recursive algorithm to compute b3k, where b is a real number and k is a positive integer. Use the fact that b3k+1=(b3k)3.arrow_forwardPython Recursion, no loopsarrow_forward
