func5 :: (Int -> Int) -> Int -> (Int, Int)
func5 f x = (x, f x)
Using map and the function above, write a function that takes a list of Ints and a function (Int -> Int) and returns a new list of tuples, with the first element being the original element, and the second being the result of the transformation.
e.g. [1,2,3] becomes [(1,1), (2, 4), (3, 9)] if the function passed in returns the square of an element
figured it out myself thank you though
makeATuple :: [Int] -> (Int -> Int) ->
[(Int,Int)]
makeATuple x f = map (\x -> func5 f x) x
Homework Answers
The function will be as below:
listToTuple :: [Int] -> (Int -> Int) ->
[(Int,Int)]
listToTuple x f = map (\x ->(x ,func5 f x)) x
[1,2,3] becomes [(1,1), (2, 4), (3, 9)] by applying this above
function

Please use Haskell, thank you! For this question, you will implement (under specific constraints) a recursive function in Haskell that takes a list of characters as an argument and returns a list that contains only every third element from the argument list in the same order. As a clarifying example, this function, when passed the argument list “ABCDEFGHIJKLMNO”, should return the list “ CFILO”. It should also be noted that your function must work (i.e., not terminate with an error)...

Haskell code: checkIfEven :: Int -> Bool x <- readLn let checkIfEven x = (even ((x*3)+1)) print checkIfEven Getting error : Variable not in scope: checkIfEven :: Int -> Bool, how to fix it? note: function goal is take an int and return a bool. takes the integer multiplies it by 3 and adds 1. if the the outcome is even return true, otherwise false.

write the following functions in Picat, Haskell, or python using recursion. 1. member(x, lst): this function checks to see if x occurs in lst. 2. sorted_list( lst): this function checks if lst is sorted in ascending order 3. Cartesian(xs, ys): this function takes two sets represented as lists, xs and us,, and returns the Cartesian product of the set, I.e a set of all possible pairs (x, y), where x is an element of xs, and y is an element...

Map, Filter, and Reduce are three functions commonly used in functional programming. For this assignment you will be implementing all three, along with three minor functions that can be passed to them. Map The map function takes as arguments a function pointer and a integer vector pointer. It applies the function to every element in the vector, storing the results in-order in a new vector. It then returns a pointer to a new vector. You should pass your square function...
