Answer the given question with a proper explanation and step-by-step solution. 3. Draw the recursion tree when n = 8, where n represents the length of the array, for the following recursive method:int sum(int[] array, int first, int last) {if (first == last)return array[first];int mid = (first + last) / 2;return sum(array, first, mid) + sum(array, mid + 1, last);} Determine a formula that counts the numbers of nodes in the recursion tree. What is the Big- for execution time? Determine a formula that expresses the height of the tree. What is the Big- for memory? Write an iterative solution for this same problem and compare its efficiency with this recursive solution. 4.

Finish the splitOdd10 using recursion to determine if the elements of an array can be split into two groups such that the sum of one group is a non-zero multiple of 10 and the sum of the other group is odd
I just need the method they are asking for Write a recursive function that takes a start index, array of integers, and a target sum. Your goal is to find whether a subset of the array of integers adds up to the target sum. The start index is initially 0.A target sum of 0 is true for any array. Examples: subsetSum(0, {2, 4, 8}, 10) -> true public boolean subsetSum(int start, int[] nums, int target) { }
Attached is a programming problem and its Java solution. My questions regarding the recursion part: 1. Say my input is "ab". When "str.length()==0" evaluates true for the first time, "ab" is printed. The str.length is already 0, how can the recursion proceed with "char ch = str.charAt(i)"? The str seems to magically restore itself back to "ab" after each permutation gets printed. Why?
By using java, Write a recursive function that finds the maximum element in an array ofintegers, based on comparing the first element in the array against themaximum in the rest of the array recursively.
You want to design an algorithm, called minMax(A,p,r), that takes an array of integers and indexes of the first and last elements, and returns the minimum and maximum values in that range. Now write the pseudo code of a divide and conquer (and therefore, recursive) algorithm with the same time complexity (Θ(n)). You can assume that p ≤ r. Also, in your code, you can return two numbers by returning a pair, e.g. “return (a, b)”, and can save the output in a similar way, e.g. “(a, b) = minMax(parameters)”. (Short answer please)
The Tower of Hanoi is a puzzle where n disks of different sizes arestacked in ascending order on one rod and there are two other rods with nodisks on them. The objective is to move all disks from the first rod to thethird, such that:- only one disk is moved at a time- a larger disk can never be placed on top of a smaller oneWrite a recursive function that outputs the sequence of steps needed tosolve the puzzle with n disks.Write a test program in C++ that allows the user to input number of disks andthen uses your function to output the steps needed to solve the puzzle.Hint: If you could move up n−1 of the disks from the first post to thethird post using the second post as a spare, the last disk could be moved fromthe first post to the second post. Then by using the same technique you canmove the n−1 disks from the third post to the second post, using the firstdisk as a spare. There! You have the puzzle solved. You only have to decidewhat the nonrecursive case is, what the recursive…

Implement a recursive procedure in UCBLogo, which will draw a set of circles arranged in a circle. It must be possible to specify the number of circles that have to be drawn in a simple fashion (i.e. with minor modification to the program source code).
PYTHON! Can someone explain this recursion problem? In my mind the ouput would be 19 because: 1st step: R(5) = -1 because (5-1)-5 then returns to top with -1 and since that is less than zero it returns 20 but subtracts the -1 it returned def R(n): if n<=0: return 20 return R(n-1) - n print(R(5))
Attached is a programming question and its Java solution. My question regarding the recursion part: 1. "arr.add(j)" but then "arr.remove(arr.size() - 1)" follows soon after, and I think nothing should be printed. How does the program still print out permutations? Is it because the recursive method call only recurse all instructions from the start of the recursion method to that line? Otherwise, say the input is "5", how does "5=1+1+1+1+1" get printed? 2. Does the recursion stop when "j<=n" evaluates false because of "for(int j = i; j <= n; j++)"? Otherwise, which line of code tells the recursion to stop?
