Question Completion with Options:
O tabs
O comma (,)
O colon (:)
O backtick (')
Answer:
In many UNIX/Linux data and configuration files are "fields". Sometimes these fields are separated by:
O tabs
O comma (,)
O colon (:)
Explanation:
A UNIX/Linux data and configuration file is a local program file that controls the operation of the program. Such files are usually static and are not created to be in executable binary. The files are stored in subdirectories. Backticks are not used to separate fields. But tabs, commas, and colons can be freely used. Configuration files, which are coded, provide the required parameters and initial settings to operate computer applications. Data files are not executable like configuration files but are used by applications as input and output data to be read or viewed.

Answer:
Explanation:
For the Program plan:
1. Two lists are structurally equal if they have the same list structure, although their atoms may be different.
2. So we are going to write a function that will check if elements in both lists at same position are atoms or not.
3. If yes then it should return true else false.
Program:
#lang scheme
( define (structurally-equal list1 list2)
(cond ((and (null? list1) (null? list2)) #t)
((or (null? list1) (null? list2)) #f)
((and (atom? (car list1)) (atom? (car list2)))
(structurally-equal (cdr list1) (cdr list2)))
((or (atom? (car list1)) (atom? (car list2))) #f)
(else (and (structurally-equal (car list1) (car list2))
(structurally-equal (cdr list1) (cdr list2) )))))
( define (atom? x) (not (or (pair? x) (null? x))))
