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!

Answer:
for i in range(1, 6):
print(("# " * i).rstrip())
Explanation:
You need to print one hashtag, then 2, then 3, and so on. We can use Python's string multiplication to get each line quicker.
String multiplication is an easy way to repeat the same string a certain number of times. It's done by multiplying the string to a number.
For example,
"hello" * 6
>> "hellohellohellohellohellohello"
If we multiply the string "#" by any number, we would get a number of hashtags side by side, without any space. To easily avoid this, we can multiply "# " instead to automatically put a space to the right of each hashtag.
We can use a for loop that goes through range(1, 6) to print out 5 rows.
for i in range(1, 6):
Then, we can print the string "# " multiplied by i.
print("# " * i)
However, this will also put a space at the end of the string, which we do not want to print. Hence, we can use the .rstrip() method to strip the string of any spaces on the right. We will first put the whole string in parentheses, then invoke rstrip on it.
print(("# " * i).rstrip())
Let's put both lines together.
for i in range(1, 6):
print(("# " * i).rstrip())
