Please help me with Haskell structure question. Thank you

Define function least that receives three numbers and returns the least value, in the following cases.

(a) Use min function.

(b) Use if-expressions.

Answer 1

Answer #1

"least" function definition :

(a). Using min function
least :: Int -> Int -> Int -> Int
least a b c = min a (min b c)

(b). Using if-expression

least :: Int -> Int -> Int -> Int

least a b c = a, if a < b && a < c

= b, if b < a && b < c

= c, if c <a && c < b

Haskell Define function-divisors that receives a number and returns a list of all divisors of that number.For example, if the input is 20, then the output would be[1,2,4,5,10,20]. You may use list comprehension, list ranges, and function mod for this purpose.Hint:Given numbern, consider all numbers from 1 ton, and then keep only the ones that dividen.

(IN HASKELL) Declare the type and define a function (say fun) that takes two whole numbers (say m and n) as input. The function then returns m ^ n. That is, m to the power of n. Please use recursion only, you should not use m ^ n, or pow or any other library function, only recursion.

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)...

Write another function buddies(...) that receives a list (with at least 3 integer numbers), and returns the number of pairs of buddies in the list. We will define a “pair of buddies” to be the pair of elements that are contiguous in the list and that are equal, and also so that the contiguous elements to the pair are different (or the pair is in an extreme of the list). For example, [5,2,2,3] has 1 pair of buddies (the 2’s)...

Define a function add_nums_x_pos_given_list_nums (..) which receives a list that is guaranteed to only have numbers (or the empty list) and returns the sum of each number multiplied by the position where the number is. (In the case of the empty list the function it will return 0) For example add_nums_x_pos_given_list_nums ([10,20,30]) will return the value 80 which is the result of adding: 0 * 10 (10 is in position 0 in the list) + 1 * 20 + 2...
