Step by Step solution about How to resolve the algorithm N'th step by step in the Haskell programming language

The provided Haskell code defines an array ordSuffs that maps integers to their corresponding ordinal suffixes (e.g., "1st", "2nd", etc.). It also defines a function ordSuff that takes an integer and returns its ordinal suffix, and a function printOrdSuffs that takes a list of integers and prints their ordinal suffixes separated by spaces. The main function calls printOrdSuffs on three different lists of integers. Here is a detailed explanation of the code:

1. Importing Libraries: The code imports the Data.Array module, which provides functions for working with arrays.

2. Ordinals Suffixes Array: The ordSuffs array is defined using the listArray function, which creates an array from a list of values. The array has a range from 0 to 9, and the values are the corresponding ordinal suffixes ("th", "st", "nd", "rd", "th", "th", "th", "th", "th", "th").

3. Ordinal Suffix Function: The ordSuff function takes an integer n as input and returns its ordinal suffix as a string. It uses the show function to convert the integer to a string, and then appends the appropriate suffix based on the value of n. If n is between 11 and 13 (inclusive), the suffix "th" is used. Otherwise, the suffix is retrieved from the ordSuffs array using the ! operator, which accesses the value at a specific index.

4. Print Ordinal Suffixes: The printOrdSuffs function takes a list of integers as input and prints their ordinal suffixes separated by spaces. It uses the unwords function to concatenate the list of strings into a single string, and then prints the result using putStrLn.

5. Main Function: The main function calls printOrdSuffs on three different lists of integers: [0..25], [250..265], and [1000..1025]. These lists represent ranges of integers, and the .. operator creates a list of all integers within the specified range (inclusive).

Overall, this code provides a way to generate and print ordinal suffixes for a given list of integers. It demonstrates the use of arrays, pattern matching, and list manipulation in Haskell.

import Data.Array

ordSuffs :: Array Integer String
ordSuffs = listArray (0,9) ["th", "st", "nd", "rd", "th",
                            "th", "th", "th", "th", "th"]

ordSuff :: Integer -> String
ordSuff n = show n ++ suff n
  where suff m | (m `rem` 100) >= 11 && (m `rem` 100) <= 13 = "th"
               | otherwise          = ordSuffs ! (m `rem` 10)

printOrdSuffs :: [Integer] -> IO ()
printOrdSuffs = putStrLn . unwords . map ordSuff

main :: IO ()
main = do
  printOrdSuffs [   0..  25]
  printOrdSuffs [ 250.. 265]
  printOrdSuffs [1000..1025]
