(Recursion and Backtracking)
Write the pseudo code for a recursive method called addB2D that takes two binary numbers as strings, adds the numbers and returns the result as a decimal integer. For example, addB2D(‘‘101’’, ‘‘11’’) should return 8 (because the strings are binary representation of 5 and 3, respectively).
Your solution should not just simply convert the binary numbers to decimal numbers and add the re- sults. An acceptable solution tries to find the sum by just directly processing the binary representations without at first converting them to decimal values.

Consider the following recursive algorithm for computing the sum of the first n cube: S(n) = 1³ +23³ +3³ +...+n³. Algorithm S(n) //Input: A positive integer n //Output: The sum of the first n cubes if n = 1 return 1 else return S(n − 1) +n*n*n a) Set up and solve a recurrence relation for the number of times the algorithm's basic operation is executed. b) How does this algorithm compare with the straightforward non-recursive algorithm for computing this function?arrow_forwardUnder your module imports, paste the following definitions: (define WIDTH 300) (define HEIGHT 160) (define ES (empty-scene WIDTH HEIGHT)) (define (next-size s) (/ s 2)) Write a tail-call recursive function called circles in Racket. This function should take two numbers, x and size, and a Scene scn. If size is less-than or equal to 2, then your function returns the scn unchanged (base case). Otherwise, your function should place a circle in the Scene that results from a recursive call to circles with x shifted by (+size (next-size size)), a new size of (next-size size), and using the original Scene. After evaluating (circles 100 48 ES), your function should output this image of five blue circles, in this order, with the first circle at (x,y) coordinate position (100, 80):arrow_forward
- Ex. 01 : Recursion About So far, we have learned that we can perform repetitive tasks using loops. However, another way is by creating methods that call themselves. This programming technique is called recursion and, a method that calls itself within it's own body is called a recursive method. One use of recursion is to perform repetitive tasks instead of using loops, since some problems seem to be solved more naturally with recursion than with loops. To solve a problem using recursion, it is broken down into sub-problems. Each sub-problem is similar to the original problem, but smaller in size. You can apply the same approach to each sub-problem to solve it recursively. All recursive methods use conditional tests to either 1. stop or 2. continue the recursion. Each recursive method has the following characteristics: 1. end/terminating case: One or more end cases to stop the recursion. 2. recursive case: reduces the problem in to smaller sub-problems, until it reaches (becomes) the end…arrow_forwardQuestion 4: (Find the minimum value in an array) Write a program that include a recursive function "recursiveMinimnm" that takes an integer array and the array size as arguments and returns the smallest element of the array. The function should stop processing and return when it receives an array of one element. Answer (2.5)arrow_forwardDont copy.Please give only correct and detailed answer.

- Python only** Use recursive function* Define countBetween with 2 parameters Use def to define countBetween with 2 parameters thas two parameters: a starting number and an ending number, and counts up (i.e., prints consecutive integers) from the starting number to the ending number. If the numbers are the same, it just prints that number; if the ending number is lower than the starting number, it prints nothing. Do not use any kind of loop Within the definition of countBetween with 2 parameters, do not use any kind of loop. Call countBetween Within the definition of countBetween with 2 parameters, call countBetween in at least one place. Python only** Use recursive function* Define countThereAndBack with 2 parameters Use def to define countThereAndBack with 2 parameters after reaching the ending number, it also counts back down to the starting number. It accepts the same two parameters defining starting and ending numbers it should print nothing if the starting number is…arrow_forward(Random sentences and story writer) Write an app that uses random-number generation to create sentences. Use four arrays of strings, called article, noun, verb andprepostion. Create a sentence by selecting a word at random from each array in the following order: article, noun, verb, preposition, article, noun.As each word is picked, concatenate it to the previous words in the sentence. The words should be separated by spaces. When the sentence is output, it should start witha capital letter and end with a period. The program should generate 10 sentences and output them to a text box. The arrays should be filled as follows:The article array should contain the articles "the", "a", "one", "some" and "any";The noun array should contain the nouns "boy", "girl", "dog", "town", "car";The verb array should contain the past tense verbs "drove", "jumped", "ran", "walked" and "skipped";The preposition array should contain the preposotions "to", "from", "over", "under" and "on";arrow_forwardWrite a recursive function to sort an array of integers into ascending order using the following idea: the function must place the smallest element in the first position, then sort the rest of the array by a recursive call. This is a recursive version of the selection sort. (Note: You will probably want to call an auxiliary function that finds the index of the smallest item in the array. Make sure that the sorting function itself is recursive. Any auxiliary function that you use may be either recursive or iterative.) Embed your sort function in a driver program to test it. Turn in the entire program and the output.arrow_forward
- Which of the following statements are correct? Iteration is always worse than recursion. Recursion uses more memory than an iterative approach. Recursion uses less memory than an iterative approach. O Iterative function is always easier to write than recursion.arrow_forward(Mathematical Analysis of Non-recursive Algorithms) 6.
