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

Write a recursive function called Rev takes a string argument (str) and and integerargument(i – the initial string position). Rev prints the str in reverse. You may not useany built-in reverse function or method. You may use string’s length method.

How is it controlled that a recursion function be called several times? What kind of command and control structure is employed in this case?

What is the functionality of base case(s) ? Group of answer choices: Call other base cases Make recursive function call Checks the logical error To complete the recursion What is the functionality of base case(s) ? Group of answer choices: Call other base cases Make recursive function call Checks the logical error To complete the recursion What is the functionality of recursive helper method ? Group of answer choices: Define base cases and recursive cases Extends the original recursive method Makes infinite function calls Make function calls to original recursive method A recursion function can be implemented without pending operations. Group of answer choices: True False

describe a recursive function that cannot be rewritten as non recursive

2. Sum: a recursive function that computes the sum of integers 1, 2, 3, ...., n for a given number n. So Sum(6) should return 1 + 2 + 3 + 4 + 5 + 6 , i.e. 21.sum(n) = n + sum(n-1)

Write a recursive function (Java) called Fac which takes one positive integer argument (n) and returns n! You may not use a built-in factorial method or function.

The 4th problem mimics the situation where eagles flying in the sky can be spotted and counted.FindEagles: a recursive function that examines and counts the number of objects (eagles) in aphotograph. The data is in a two-dimensional grid of cells, each of which may be empty (value 0) orfilled (value 1 to 9). Maximum grid size is 50 x 50. The filled cells that are connected form an object(eagle). Two cells are connected if they are vertically, horizontally, or diagonally adjacent. Thefollowing figure shows 3 x 4 grids with 3 eagles. 0 0 1 21 0 0 01 0 3 1 FindEagle function takes as parameters the 2-D array and the x-y coordinates of a cell that is a part ofan eagle (non-zero value) and erases (change to 0) the image of an eagle. The function FindEagleshould return an integer value that counts how many cells has been counted as part of an eagle and havebeen erased. The following sample data has two pictures, the first one is 3 x 4, and the second one is 5 x 5 grids. Notethat your program...

A recursive function must have a to end the recursion. recursive call base case O value boolean condition

Identify the base case in this recursive function. Assume i> 0 when the function is invoked. (Line numbers are not part of the code.) 1. def add(i, j): 2. if i == 0: 3. return j 4. else: 5. return add(i - 1, j + 1) This function has no base case O line 5 line 1 line 4 O line 2 Question 6 The following recursive function is supposed to return a list that is the reverse of the list it was given. But it has a bug. What is the bug? (Line numbers are not part of the code.) MooP eok Dr

When a recursive function is run, there is an additional demand placed on the memory of the computer and the amount of time it takes to run the programme.

What is the purpose of the base case in a recursive function? A. The base case starts off the recursive process. B. The base case defines the basis for the function calling itself. C. The base case is what stops the recursive process. D. All of the above are true. E. None of the above are true.
