Indirect recursion is when function A calls
function B, which in turn calls function A.
is it true or false.

- How is it controlled that a recursion function be called several times? What kind of command and control structure is employed in this case?arrow_forwardRecursive Exponentiation (using c language) Write a recursive function power(base, exponent) that when invoked returns baseexponent. For example, power(3, 4) = 3 * 3 * 3 * 3. Assume that exponent is an integer greater than or equal to 1. Then, write a demo program that uses the power function and test it out for a number of inputs. Hint: The recursion step would use the relationship baseexponent = base * baseexponent–1 and the terminating condition occurs when exponent is equal to 1 because base1 = basearrow_forwardWhich of the basic data structures is the most suitable if you only need to implement recursion in a programming language? When you make a recursive call, you need to save the function you are currently in and its parameters values in some data structure, so that when you go out of the recursion you can restore the state. When you go out of the recursive call, you will always need to extract the last element that was put in the data structure. A. Queue B. Stackarrow_forward

- What are the performance considerations when using function objects in a recursive manner?arrow_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_forwardDefine the term " recursion base case " .arrow_forward
