Implement this function import java.util.ArrayList;public interface PermuteAL {*** Creates a sequence of numbers.Thus, sequence(3) generates [0,1,2].ArrayList sequence(int n);/*** Permute the elements of the array.Step 1: if the size of the input array, arr, is 1來add it to the result and return it. Done.* Step 3: for each element i of the list arr, createa new and smaller list, sm, with that element removed.To copy a ArrayList, you can pass it into the constructorof ArrayList. The code below copies arr into sm.ArrayList sm = new ArrayList<>(arr);Step 3: call permutation on the smaller list andstore the result in ires.Step 4: for each list in ires, create a newlist by appending the element i of arr.Add the return value of append to result.Step 5: return the result.* /ArrayList> permutation(ArrayList arr);DELL

Question: First write a function mulByDigit :: Int -> BigInt -> BigInt which takes an integer digit and a big integer, and returns the big integer list which is the result of multiplying the big integer with the digit. You should get the following behavior: ghci> mulByDigit 9 [9,9,9,9] [8,9,9,9,1] Your implementation should not be recursive. Now, using mulByDigit, fill in the implementation of bigMul :: BigInt -> BigInt -> BigInt Again, you have to fill in implementations for f , base , args only. Once you are done, you should get the following behavior at the prompt: ghci> bigMul [9,9,9,9] [9,9,9,9] [9,9,9,8,0,0,0,1] ghci> bigMul [9,9,9,9,9] [9,9,9,9,9] [9,9,9,9,8,0,0,0,0,1] ghci> bigMul [4,3,7,2] [1,6,3,2,9] [7,1,3,9,0,3,8,8] ghci> bigMul [9,9,9,9] [0] [] Your implementation should not be recursive.

Please IN C++ Write the simplest program that will demonstrate iteration vs recursion using the following guidelines - Write two primary helper functions - one iterative (IsArrayPrimeIter) and one recursive (IsArrayPrimeRecur) - each of which Takes an array of integers and its size as input params and returns a bool such that 'true' ==> all elements of the array are prime, so the array is prime, 'false' ==> at least one element in array is not prime, so array is not prime. Print out a message "Entering <function_name>" as the first executed statement of each function. Perform the code to test whether every element of the array is a Prime number. Print out a message "Leaving <function_name>" as the last executed statement before returning from the function. Remember - there will be nested loops for the iterative function and there can be no loops at all in the recursive function. For the recursive function - define one other helper function (IsPrimeRecur) which…

In c++ please help me answer this question I will give you a good rating :) implement the three versions of the addupto20() function: iterative, recursive, and divide-and-conquer approach test these functions with a few inputs from your main() Iterative solution * check if there exsits two numbers from vector data that add up to 20 e.g., if data=[2,5,3,15], the function returns true, as data [0] +data [3]==20 e.g., if data=[3,4,0,8], the function return false precondition: vector data has been initialized postcondition: if there are two numbers from list add up to 20, return true; otherwise, return false */ bool AddupTo20 (const vector‹int> & data){ } Come up with a recursive solution to the problem, following the hints given below: * check if there exsits two numbers from vector data[first...right] add up to 20 e.g., if data=[2,5,3,15], first=0, last=3, the function returns true, as data [0] +data [3]==20 e.g., if data=[2,5,3,15], first=2, last=3, the function returns…

Need some help with this c++ recursive function: Write the function int countEights(int n). Inside the function, compute recursively (no loops) the count of the occurrences of 8 as a digit inside the parameter n. Except that an 8 with another 8 immediately to its left counts double, so 8818 yields 4. Note that mod (%) by 10 yields the rightmost digit (126 % 10 is 6), while divide (/) by 10 removes the rightmost digit (126 / 10 is 12). Here are some examples: countEights(8) returns 1 countEights(818 returns 2 countEights(8818) returns 4
Use Clojure: a. See attached picture. b. In Clojure (like other functional programming languages) functions and variables are treated identically. This means a function may easily take another function as an argument, and/or return a function. Write a function swap-arg-order which takes a function (of two arguments) as an argument returns another function that does the same thing, but expects its two arguments in the opposite order.That is, for example• given the division function / which divides the first argument by the second (so (/ 3 6) returns the number 1/2), the following expression should evaluate to 2((swap-arg-order /) 3 6)• given the function list-longer-than? from above, the following expression should evaluate to true((swap-arg-order list-longer-than?) '(1 2 3) 2) c. Define a higher order function g so the following expression evaluates to true:(= 100 (g (fn [n] (* n n))))

I need this function to be defined using Haskell language. Hailstone sequences are produced by repeatedly applying the following mapping to numbers: an even number n maps to n/2 and an odd number m maps to 3m+1.The function hailmap applies this transformation to a single integer.hailmap :: Integer -> Integerhailmap n = undefined Note: when the function is called using an integer the answer will be given based on the number being odd or even. -- ghci> hailmap 7-- 22-- ghci> hailmap 8-- 4 Note: Use div rather than / for division, to avoid the need for conversion between numeric types.-- ghci> 15 `div` 2-- 7
