### Select Multiples Function in Scheme**Objective:**Develop a function named `select-multiples` that processes an integer and a list of integers, utilizing `fold` (or `reduce`) to generate a list containing elements that are multiples of the given integer.### Requirements:- **Use of `fold` or `reduce`:** - Primarily employ `fold` or `reduce` for the task. - Minimal processing can occur outside the `fold` call.- **Library Requirements:** - Employ the built-in `fold` method by incorporating `(require 'list-lib)`, or alternatively, craft a custom implementation. - The `select` function is not permitted.### Parameters:The built-in `fold` function requires parameters in the format: `action partial-result lst`.### Multiplicity Check:Determine if a number (`num`) is a multiple of another (`value`) by verifying if `(mod num value)` equals `0`.### Examples:1. `(my-select 5 '(5))` should return `(5)`.2. `(my-select 3 '(7 9))` should return `()`.3. `(my-select 5 '(1 15 25))` should return `(15 25)`.4. `(my-select 2 '())` should return `()`.

In the select-multiples function, we use fold to iterate through the list of integers lst. For each…

Write a function named select-multiples value 1st in Scheme that takes an integer and a list of integers and uses fold (or reduce) to return list of elements that are multiples of value. You must use either fold or reduce to do the vast majority of the work. (You may do a little pre- and post- processing outside the call to fold.) You may use the built-in fold method by adding the line (require 'list-lib), or you can use your own implementation. You may not use the built-in select function. The built-in fold function has parameters in this order: action partial-result lst. You can detect whether num is a multiple of value by checking whether (mod num value) is 0. For example, (my-select 5 (5)) should return (5) ● (my-select 3 '(7 9)) should return () • (my-select 5 '(1 15 25)) should return (15 25) (my-select 2 '()) should return () ●

7. Given two lists A and B, write a function to compute the difference A – B, where A – B is the list of elements that are in A but not in B. For example, if A is '(6 7 8 9) and B is (7 9) then A – B is '(6 8).
I am new to Haskell and I need someone to explain the syntax of this function. The function is supposed to take a single integer parameter. It indicates the maximum value of Fibonacci numbers that will be in the list and it uses recursion to generate the list. fibList n = go n 1 1 where go n f s | (f+s) > n = [] | otherwise = (f+s) : go n s (f+s)
Write a recursive function that finds the number of occurrences of a specified character in a list. You need to define the following two functions. The second one is a recursive helper function.def count(chars, ch):def countHelper(chars, ch, high):Write a test program that prompts the user to enter a list of characters in one line, and a character, and displays the number of occurrences of the character in the list.

c++ Write a function called MinWindowSubstring(Text subText) that takes a struct object of type Text as shown below and has two elemnts: the first element Sentence which is a long sentence or string, and the second element sub is a string contains some characters. Your goal is to determine the smallest substring of Sentence that contains all the characters in sub. For example: if subText is Senetnce="aaabaaddae", sub="aed" then the smallest substring of Sentence that contains the characters a, e, and d is "dae" located at the end of the string. So for this example your program should return the string dae. Your program must contain and use the following: A struct called Text that will be used to store each position. struct Text { string Sentence; string sub; }; A function called MinWindowSubstring that will calculate and return the minimum substring of a senetence, which will be called by your main function. string MinWindowSubstring(Text subText); Input: The first…
About initial programming in python: Create a function that receives as parameters a list of 4 elements [name,[phone(s)], email, instagram] and a phone number:• If the phone number is in the list, it must be removed.• If not, no updates will be made. Note: phone(s) is within another list. Your function should only return a Boolean value, indicating whether the change was made or not. To find out if the function did the phone deletion correctly, you should check the contents of the list with the contact details you used to test your function after executing it. In the image is the model of parameters, in this case the function must exclude from the list of 4 elements the indicated number '44322456' and return "True".
In c++ and please without the use of vectors. Thanks very much! A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use linear search. Modify the algorithm to output the count of how many comparisons were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Joe 123-5432 Linda 983-4123…
