Write a Haskell script called HelloWorld.hs that prints "Hello World!" in the following ways:
1. Use one ptrStrLn. Recall: putStrLn :: String -> 10
() writes a string and moves to a new line.
2. Uses the do function, putStr, and putChar, with the two strings: "Hello" and "World!". Recall: putStr:: String -> 10 () writes a string without moving to a new line, and putChar:: Char -> IO () writes a single character to the screen.
Answers
Sure, here's the Haskell script for you:
-- HelloWorld.hs
Explanation:
let's dive a bit deeper into the Haskell script for printing "Hello World!" in two different ways:
-- Method 1: Using putStrLn
main = putStrLn "Hello World!"
In this method, we use the putStrLn function, which takes a string as an argument and prints it to the console, followed by a newline character to move to the next line. The main function is the entry point of a Haskell program, so this line of code tells the compiler to print "Hello World!" to the console when the program runs.
-- Method 2: Using do function, putStr, and putChar
main = do
putStr "Hello "
putChar 'W'
putChar 'o'
putChar 'r'
putChar 'l'
putChar 'd'
putStrLn "!"
In this method, we use a combination of the do function, putStr, and putChar functions to print "Hello World!" to the console. The do function is used to sequence multiple IO actions, which are the putStr and putChar functions in this case.
putStr takes a string as an argument and prints it to the console, without adding a newline character. Here, we use it to print the string "Hello".
putChar takes a single character as an argument and prints it to the console. In this case, we use it to print each letter of the string "World!" one by one, since putChar can only print one character at a time.
Finally, we use putStrLn to print the exclamation mark and move to a new line. Since we used putStr earlier, we need to use putStrLn here to make sure we move to a new line before printing the exclamation mark.
So there you have it, two different ways to print "Hello World!" in Haskell!

a passcode must have exactly 5 digits. digits cannot be repeated, the passcode must begin with an odd number and 0s cannot be used anywhere in the passcode. how many different passcodes are possible?
Answers
The number of possible passcodes that meet the requirements of having exactly 5 digits, beginning with an odd number, and not using any 0s or repeated digits is 120.
Since the passcode must have exactly 5 digits, and the first digit must be an odd number, there are 5 choices for the first digit (1, 3, 5, 7, or 9).
After choosing the first digit, there are only 4 choices left for the second digit, since it cannot be the same as the first digit. For the third digit, there are only 3 choices left, since it cannot be the same as the first two digits. Similarly, there are only 2 choices left for the fourth digit, and only 1 choice left for the fifth digit.
Therefore, the total number of possible passcodes is:
5 x 4 x 3 x 2 x 1 = 120
Hence,
the number of possible passcodes is 120.

At which of the capability maturity model integration maturity levels, are processes well defined, understood, and consistent across the organization?.
Answers
At defined (quantitatively managed), the capability maturity model integration maturity levels, are processes well defined, understood, and consistent across the organization.
An organization's software development process can be developed and improved using the Capability Maturity Model (CMM). The model outlines a five-level evolutionary path of processes that get more ordered and systematic as they mature.
The Software Engineering Institute (SEI), a research and development facility supported by the U.S. Department of Defense (DOD) and now a part of Carnegie Mellon University, developed and promotes CMM. In order to address software engineering difficulties and, generally speaking, develop software engineering approaches, SEI was established in 1984.
More specifically, SEI was created to streamline the DOD's software-intensive system development, acquisition, and maintenance processes. SEI supports the widespread industrial use of CMM Integration (CMMI), a development of CMM. Additionally, the capability maturity model is still commonly employed.
CMM is comparable to ISO 9001, one of the International Organization for Standardization's ISO 9000 set of standards. The ISO 9000 standards outline an efficient quality system for the manufacturing and service sectors; ISO 9001 explicitly addresses the creation and upkeep of software.

Answers
Decrypting the encrypted three-letter word 417 given the public key (n=45 173, e=5):Here, n= 45 173, e= 5. We know that c=417 as it is given in the question. So, to get the plaintext message we need to use the following formula: plaintext = c^ d mod n, where d is the private key.
To calculate d, we need to use the formula, d = e^-1 mod (p-1)(q-1), where p and q are the prime factors of n. We know that n=45 173=193 * 233. So, p=193, q=233. Using the formula, d = e^-1 mod (p-1)(q-1) = 5^-1 mod (192 * 232) = 92101 To calculate the plaintext, we use the formula, plaintext = c^d mod n = 417^92101 mod 45 173 = 703. So, the decrypted three-letter word 417 is mapped to "703" using the mapping A..Z to 1..26.
The decrypted three-letter word is GCH. Decrypting the encrypted three-letter word 15907 given the public key (n=91 687, e=7), Here, n= 91 687, e= 7.

I want to write a function that creates a dictionary of how many friends each person has. People can have 0 to many friends.
Answers
Python function that counts the neighbors for each node in a graph,
def count_neighbors(graph):
return {person: sum(person in pair for pair in graph) for pair in graph for person in pair}
Here's a Python function that counts the number of neighbors for each person in a given graph:
def count_neighbors(graph):
neighbors = {}
for pair in graph:
for person in pair:
if person not in neighbors:
neighbors[person] = 0
neighbors[person] += 1
for person in neighbors:
if person not in [pair[1] for pair in graph]:
neighbors[person] = 0
return neighbors
To use this function, you can pass your graph (list of lists) as the input and it will return a dictionary where the keys represent people and the values represent the number of friends they have.
Here's an example usage:
graph = [['A', 'B'], ['B', 'C'], ['B', 'D'], ['E']]
result = count_neighbors(graph)
print(result) # Output: {'A': 1, 'B': 3, 'C': 1, 'D': 1, 'E': 0}
In this example, the graph variable represents the input graph. The count_neighbors function is called with the graph as the argument, and the result is stored in the result variable. Finally, the result is printed to the console.

What is programming?Programming is a technological process that instructs a computer on which tasks to perform in order to solve problems.
The output of the method call mystery(123456) will be 123456 printed on the console.
The mystery method takes an integer argument x and prints the digits of x in reverse order recursively. The base case is when x is less than 10 (i.e., only one digit is left to print).
Otherwise, the method calls itself with x/10 to remove the rightmost digit, then prints the remainder of x divided by 10 (i.e., the rightmost digit).
In the case of mystery(123456), the method is called recursively as follows:
mystery(12345) prints 6mystery(1234) prints 5mystery(123) prints 4mystery(12) prints 3mystery(1) prints 2Finally, the method is called with mystery(0) (the base case), and nothing is printed. Therefore, the output on the console is 123456.

to find salary using HLookup
how to find rate using HLookup
how to find commission HLookup
Answers
To find salary, rate, or commission using HLOOKUP, you would need a table or range where the desired values are arranged in a row or rows, with the lookup value located in the top row.
HLOOKUP is a function in Excel that allows you to search for a specific value in the top row of a table or range and return the corresponding value from a specified row. To find salary, rate, or commission using HLOOKUP, you would need a table or range where the desired values are arranged in a row or rows, with the lookup value located in the top row.
In HLOOKUP, you would specify the lookup value (such as an employee name or ID) and the range of cells that contains the table. The function would then search for the lookup value in the top row of the table and return the corresponding value from a specified row.
For example, if you have a table with employee names in the top row, salaries in the second row, rates in the third row, and commissions in the fourth row, you can use HLOOKUP to find the salary, rate, or commission for a specific employee by specifying the lookup value and the appropriate row index.
In the HLOOKUP formula, the lookup value would be the employee name or ID, the table range would include the top row containing the employee names, and the row index would be specified to determine which row of the table to retrieve the desired value from (e.g., 2 for salary, 3 for rate, 4 for commission). The HLOOKUP function will then return the corresponding value based on the specified lookup value and row index.
It's important to note that for HLOOKUP to work correctly, the lookup value should match exactly with the value in the top row of the table, and the table should be sorted in ascending order based on the lookup values. If an exact match is not found, HLOOKUP can use approximate matching with the help of the optional fourth argument, but this requires the table to be sorted in ascending order.
