In REXX, you can filter integers less than a given delimiter by reading the delimiter first with parse pull, then looping through the input with do while lines() > 0. For each number, use if num < delim then say num to print values below the limit. This keeps the original order, like selecting the right tools in iPhone Stardew Valley.

You are expected to write a custom filter function without using built-in methods. Just return a new list with elements less than the delimiter while preserving order. Make sure your function matches the given signature for your language.

The generate code by HR is bad. Haskell is a functional programming language and it should be a declarative style rather than imperative.

for example this processes whole input like a stream. Betpkr Much more elegant.

filterIt :: [Int] -> [String] filterIt (a:xs) = map show $ filter (\x -> x < a) xs

main = interact $ unlines . filterIt. map read. words

let readStringList() = 
    let rec loop acc = 
        let input = Console.ReadLine() 
        if input = null then 
            List.rev acc
        else 
            loop (input :: acc) 
    loop []

let delimiter = Console.ReadLine() |> int

readStringList() 
|> List.map int // Convert string to int
|> List.filter (fun x -> x < delimiter) // Filter the list 
|> List.iter (printfn "%d") // Print the list
