Function 4: my-map
In CLISP define your own function that duplicates the functionality of mapcar from the standard library. You may not use the built-in mapcar function as a helper function. Your implementation must be recursive.
· Input: The input to my-map is a function that takes a single argument and a homogeneous list of elements of the same data type compatible with the procedure. Note: the function argument can be named or anonymous (lambda).
· Output: A new list of the original elements with the same procedure applied to each.
· Examples:
> (my-map 'sqrt '(9 25 81 49))
'(3 5 9 7)
> (my-map '1+ '(6 4 8 3))
'(7 5 9 4)
> (my-map (lambda (n) (* n n)) '(5 7))
'(25 49)
> (my-map 'evenp '(2 5 7 12))
'(t NIL NIL t)

Higher-order Functions A function is called a higher-order function (also called a functional form) if it takes a function as an argument or returns a newly constructed function as a result Scheme has several built-in higher-order functions, for example apply takes a function and a list and applies the function with the elements of the list as arguments input (apply (3...

You may use the letrec form but do not use any additional forms and functions besides those we've talked about in class. (define filter (lambda (input-list func) (cond ((null? input-list) '()) ((func (car input-list)) (cons (car input-list) (filter (cdr input-list) func))) (else (filter (cdr input-list) func))))) 2.

LISP Programming Assignment
It is a good idea to start this assignment early; Lisp programming,
while not inherently difficult, often seem somewhat foreign at
first, particularly when it comes to recursion and list
manipulation. This assignment is loosely based on material by Dr.
Henri Casanova.

the greater of the two.

In C++: Write a hash.cpp that does the following: Write your own main and insert function to insert the sequence of integers 121, 81, 16, 100, 25, 0, 1, 9, 4, 36, 64, 49,) into a hash table using initial table of size 17. Implement rehashing and run the same sequence of input using initial table of size 7. You can choose any rehashing function for this part. Thanks!

Define a function called collapse() which takes a list as input. Each element of the list will either be an integer, or a list of integers. The function should modify the input list by replacing all of the elements which themselves are lists with the sum of their elements. For example: Test Result vals = [1, 2, 3, 4, 5] collapse(vals) print(vals) [1, 2, 3, 4, 5] vals = [1, [2, 3], 4, 5] collapse(vals) print(vals) [1, 5, 4, 5]...

You are to write a function called arrange. Your function will reorder a given list, where even indexed elements are arranged by descending order (based on index order) from 0 to n/2 of the list and odd indexed elements arranged in ascending order from (n/2) + 1 to n 1. Your function does not need to return the list but to change the existing...

1. Define a function in python that returns the sum of the following 4 lists. Remember to store and re- use your code instead of summing the values for each list 4 times. Hence, define a function that takes as an argument a list and returns the sum of values. Copy the following lists and paste them in a Python file after you define the sum_of_values function Call the function and pass to it a different list each call as...
