In kotlin, Write a recursive factorial function with an expression body (not a block body)

write a c++ recursive function to solve the following: str contains a single pair of parenthesis, return a new string // made of only the parenthesis and whatever those parensthesis contain. You can use substr in this problem. // // Pseudocode Example:// findParen("abc(ghj)789") => "(ghj)" // findParen("(x)7") => "(x)" // findParen("4agh(y)") => "(y)" // string findParen(string str) { }

Write a recursive Python function named pgcd, to find and return the Greatest Common Divisor (GCD) of two numbers x and y passed in parameters. • Test it gcd (1234,4321) gcd (8192,192)

In C++: Explain and show how to use the recursive function int gcd (inta, int b).

DO NOT COPY ANSWER FROM ANOTHER QUESTION LEAVE IF you cannot do it perfectly. Otherwise, I will not only DOWN the vote but also REPORT you to the official Chegg team.I won't stop calling Chegg until they really pay attention to this trash behavior. Write a structurally recursive function (prefix->postfix exp) that takes as input an expression in the same little language as Problem 4. prefix->postfix returns an expression of the same form as its input, except that all function applications have been reversed. Finish this Racket code below to answer the question above.(define prefix->postfix(lambda (exp)))

‘Write a function nesting(), which takes an arbitrary number of parameters, and returns a list containing the arguments. Write another function unnesting(), which takes a list L as the parameter and retums a 1D list. Notice that, you should be able to use loops to solve thisproblem and should not use recursive functions (which we will not cover in this course). ‘Write assertions to test the two functions.For example nesting(1, nesting(2, 3, nesting(4, 5, [6])), [7, 8], 9)unnesting([1, [2, 3, [4, 5, [6]]], [7. 8], 9]) (1, [2, 3, [4, 5, [6]]], [7, 8], 9][1, 2,3, 4, 5, 6, 7, 8 9]

e. Problem 5. Devise a function that receives a string and computes how many asterisks are in the string with a recursive method. For instance, if the input is "Able was I ere ***Elba", the function should output 3. If the input is "Peanuts", the function should return 0. Approach: Let's assume the signature of our function is countAsterisks(s) where s is the input string. In the body of your function, check if s[0] is equal to an asterisk. If the string contains only a single character and it is an asterisk, return 1. If the string contains only a single character and it is not an asterisk, return 0. If the string is longer than one character, determine if the first character is an asterisk and count it if this is the case. Then, create a new string s1 that is the same as the input string s but without the first character. Recursively call countAsterisks (s1) and return the value returned from this recursive call, plus one (if there is an asterisk in s[0]). Also, writing any explicit...

In Kotlin, Write a recursive function called myZip, with an expression body. MyZip takes two Lists and returns a List of Pairs in which each value may be any type (I suggest your start by thinking out how to represent this data type). The pairs consist of corresponding elements in the two lists (the first element of the first list and the first element of the second list, etc). The base case should be that either (or both) of the original lists has length 1, so that, if the lists have different length, the zipping stops when the first list runs out of values.

Write a recursive function in C++ to multiply all even numbers from 2 to n, where n is an input to the function, and n>=2.

1. You are to create a well-formed Python recursive function (i.e, there must be a stopping/base case and the recursive case must present a smaller problem), along with a call to that function. 2. Trace your function and call. Remember that you must keep track of memory for each function call and provide output. How would I trace a function? and keep track of its memory for each function call?

How is it regulated that a recursion function be called several times? What type of command and control structure is used here?

Write a recursive Racket function "update-if" that takes two functions, f and g, and a list xs as parameters and evaluates to a list. f will be a function that takes one parameter and evaluates true or false. g will be a function that takes one parameter and evaluates to some output. The result of update-if should be a list of items such that if x is in xs and (f x) is true, then (g x) is in the list. The output list's elements should keep the input list's items in the same relative order. For example (update-if even? add1 '(1 2 3 4)) should evaluate to '(3 5) because 2 and 4 make even? true and add1 turns 2 and 4 into 3 and 5.

program in C++ with the name, towers.cpp which helps to solve the Towers of Hanoi puzzle using this recursive approach. The main() routine should make a single call to the recursive member function do Towers(). This function then calls itself recursively until the puzzle is solved. Note: solve as soon as possible
