Answer:
cryptography
Explanation:
cryptography
In computer science, cryptography refers to secure information and communication techniques derived from mathematical concepts and a set of rule-based calculations called algorithms, to transform messages in ways that are hard to decipher
Answer:
Commands: commands are also known as "programs" and the program is a set of rules that performs a specific task which is executed by a computer.
Unix is an operating system. that supports multi-tasking and multi-user functionality. Unix is most widely used in all forms of computing systems such as desktop, laptop, and servers. It provides a Graphical user interface similar to windows.
The Unix operating system there are various commands. The list of five Unix commands can be given as:
1) cal
2) date
3) banner
4) who
5) whoami
1)cal:
The cal command stands for calender. It displays the date.
Syntax:
$ cal
or
$ cal [[month] year]
Example:
$ cal 10 2019
2)date:
The date command stands for date and time. It displays the system date and time.
Syntax:
$date
or
$ date[+format]
Example:
$ date +%d/%m/%y
3) banner
The banner command stands for display the text in to a large size.
Syntax:
$banner message
Example:
$banner Unix
4) who
The who command stands for display the list of users currently logged in.
Syntax:
$who
or
$who [option] … [file][arg1]
Example:
$who
5) whoami
The whoami command stands for display the user id of the currently logged-in user.
Syntax:
$whoami
Example:
$whoami
Explanation:
1)cal command display the current month and year.
2)date command display system date and time.
3)banner command display text in large size.
4)who command display the user name who currently login.
5)whoami command display user id.

Answer:
O(n) which is a linear space complexity
Explanation:
Space complexity is the amount of memory space needed for a program code to be executed and return results. Space complexity depends on the input space and the auxiliary space used by the algorithm.
The list or array is an integer array of 'n' items, with the memory size 4*n, which is the memory size of an integer multiplied by the number of items in the list. The listSize, i, and arithmeticSum are all integers, the memory space is 4(3) = 12. The return statement passes the content of the arithmetic variable to another variable of space 4.
The total space complexity of the algorithm is "4n + 16" which is a linear space complexity.
