Write a function in Scheme or rules in Prolog called countlt that takes a list of numbers, L, and another number, N, and returns the count of numbers less than N in the list L. Example calls Scheme: (countlt '(6 1 9) 4) -> 1 (countlt '(50 27 13) 1) -> 0 Prolog ?- countlt (I6, 1, 91, 4, X). X = 1. ?- countlt (I50, 27, 131, 1, x). x = 0.

OZ PROGRAMMING LANGUAGE Develop a function {MapTuple T F} that returns a tuple that has the same width and label as the tuple T with its fields mapped by the function F. For example, local fun {Sq X} X*X end in {MapTuple a(1 2 3) Sq} end should return a(1 4 9). Hint: A tuple is constructed with {MakeTuple L N}, where L is the label and N is the width of the tuple.
Please write in scheme language. Write a Scheme procedure that sums all the elements in a given list of numbers. It takes input from the user as a list. Then it returns sums of elements in this list of numbers. Let's say The user enters 1 2 3 4 as a list. It must be returned 10 ( 1+2+3+4=10)
Write a program in C programming language that takes two arguments at the command line, both strings. The program checks to see whether or not the second string is a substring of the first (without using the substr -- or any other library -- function). One caveat: any * in the second string can match zero or more characters in the first string, so if the input were abcd and the substring was a*c, then it would count as a substring. Also, include functionality to allow an asterisk to be taken literally if preceded by a \, and a \ is taken literally except when preceding an asterisk.
*Needs to be done in scheme interleave* Implement function interleave in scheme, which expects as arguments two lists x and y, and returns asingle list obtained by choosing elements alternately, first from x and then from y. When either x or yruns out, interleave takes the remaining elements from the other list, so that the elements of the resultare exactly the elements of the two argument lists taken together. (interleave '(1 2 3) '(a b c)) -> (1 a 2 b 3 c) (interleave '(1 2 3) '(a b c d e f)) -> (1 a 2 b 3 c d e f) (interleave '(1 2 3 4 5 6) '(a b c)) -> (1 a 2 b 3 c 4 5 6)
Suppose you have a list of key/value pairs (i.e., a nested list where each element of the list is a (key value)pair. For example, the list might look like this: '((France Paris) (France Nice) (Spain Madrid) (Poland Krakow) (Poland Warsaw)) (Notice that the keys need not be unique for this problem.) Write a function named first-occurrence in Scheme that takes a key and a list then returns the value of the first item on the list with a matching key. Return '() if none of items on the list has a matching key. You must use either fold or reduce to do the vast majority of the work. You may use the built-in foldmethod by adding the line (require 'list-lib), or you can use your own implementation. The built-in fold function has parameters in this order: action partial-result lst. You may assume that the list contains an element with the key to be updated. For example, (first-occurrence 'Germany '((France Paris) (Germany Bonn) (Germany Berlin))) should return 'Bonn (first-occurrence 'Poland…
Write the following function in Lisp: a function that takes one parameter that you can assume to be a symbol named after a day of the week (no need to check it), such as 'monday, and returns the symbol for the next day. For example, (next-day 'tuesday) should return the symbol 'wednesday. Implement this function with a complex conditional.
A. Write a Scheme function that returns the number of zeros in a given simple list of numbers.B. Write a Scheme function that returns the reverse of its simple list parameter.C. Write a Scheme predicate function that tests for the structural equality of two given lists. Two lists are structurally equal if they have the same list structure, although their atoms may be different.
rite a function numPairs that accepts two arguments, a target number and a list of numbers. The function then returns the count of pairs of numbers from the list that sum to the target number. In the first example the answer is 2 because the pairs (0,3) and (1,2) both sum to 3. The pair can be two of the same number, e.g. (2,2) but only if the two 2’s are separate twos in the list.In the last example below, there are three 2’s, so there are three different pairs (2,2) so there are 5 pairs total that sum to 4. Sample usage: >> numPairs( 3, [0,1,2,3] )2

c++ Implement a recursive function that determines whether a string is a palindrome or not. A word is a palindrome if the word looks the same when written backwards. For example. kayak → kayak, but not ball → llob. The function only needs to handle whole words. No special characters or spaces appear in the strings. You do not have to deal with case sensitivity. You get a parameter from stdin: str the text string Input Expected outputkayak 1boll 0naturrutan 1
