Recursive function:
- Recursive function is a function that calls itself during execution.
- It enables the function to repeat itself several times and outputs the result and the end of each iteration.
- Recursive programs are common in computer science since it allows programmers to write efficient programs using less amount of code.

- Write a recursive function power( base, exponent ) that when invoked returns baseexponentFor example, power( 3, 4 ) = 3 * 3 * 3 * 3. Assume that exponent is an integer greater than orequal to 1. Hint: The recursion step would use the relationship baseexponent = base * baseexponent1and the terminating condition occurs when exponent is equal to1 becausebase1 = base c languagearrow_forwardAnswer the given question with a proper explanation and step-by-step solution. Write the provided sequence as a recursive function. 1,2,4,8,16,32,dotsarrow_forwardRecursion in programming is described as when a function/method makes a direct or indirect call to itself. Which of the features is not valid for a recursive function. Select one: a. The Recursive calls can be more then one b. The Recursive Call – the function calls itself with an input which is a step closer to the stop condition c. The Stoping Conditions can be more than one d. The Recursive call is optional. e. A Stop Condition – the function returns a value when a certain condition is satisfied, without a further recursive callarrow_forward
- 8. Ackerman's Function Ackermann's Function is a recursive mathematical algorithm that can be used to test how well a system optimizes its performance of recursion. Design a function ackermann(m, n), which solves Ackermann's function. Use the following logic in your function: If m = 0 then return n + 1 If n = 0 then return ackermann(m-1,1) Otherwise, return ackermann(m-1,ackermann(m,n-1)) Once you've designed yyour function, test it by calling it with small values for m and n. Use Python.arrow_forwardFor each of the following applications, mention the data structure that will be most suitable to use. Justify your answer. a) For finding the shortest path between source and destination location. b) For implementing a recursive function, where each call to function must return to the immediate last call. c) For checking balanced parenthesis in an arithmetic expression.
