Answer:
These all are constructors.
<u>CONS</u>
(CONS A B)
makes a pair like this: (A . B)
In other words, A is the CAR of the pair; B is the CDR of the pair.
For example:
(CONS 4 5) ==> (4 . 5)
(CONS 4 '(5 6)) ==> (4 5 6)
[The pair (4 . (5 6)) is the same thing as (4 5 6)].
<u>APPEND </u>
(APPEND A B)
makes a new list by replacing the final nil in A with the list B. A and
B must be proper lists.
For example:
(APPEND '(4) '(5 6)) ==> (4 5 6)
This takes any amount of number and put in this order
<u>LIST </u>
In this ,it will return a list whose elements are value of arguments in the order as it appeared in the LIST.It can take any amount of parameters
For example,
(LIST 4) ==> (4)
(LIST 4 5) ==> (4 5)
(LIST 4 5 '(6 7)) ==> (4 5 (6 7))
(LIST (+ 5 6)(* 5 6)) ==> (8 9)

Ribbon im pretty sure is your answer
Basic understanding of code language such as Java, C++, Swift (iOS) etc. without knowledge of these, you’ll be lost trust me. Study up on these in your spare time. They do teach this stuff in college, but being ahead of the game is always good. No pun intended kek ;D
