    Scala

    def checkHeadLessThanDelim(delim: Int, head: Int, result: List[Int]
                          ): List[Int] = {
    if (head < delim) {
        result :+ head
    } else {
        result
    }
}

def f(delim: Int, arr: List[Int], result: List[Int] = List(),
     headChecker: (Int, Int, List[Int]) => List[Int] = checkHeadLessThanDelim
     ): List[Int] = {
    if (arr.size > 0) {
        f(delim, arr.tail, headChecker(delim, arr.head, result))
    } else {
        result
    }
}

    Thanks for the solution, https://www.lightweightflanges.com/ I was looking for it for my site

    filterLessThan :: Int -> [Int] -> [Int] filterLessThan _ [] = [] filterLessThan n (x:xs) | x < n = x : filterLessThan n xs | otherwise = filterLessThan n xs

    main :: IO () main = do n <- readLn :: IO Int inputdata <- getContents let numbers = map read (lines inputdata) :: [Int] putStrLn . unlines $ (map show . filterLessThan n) numbers

    Thanks for sharing this valuable JavaScript filter; otherwise, I often encounter bugs and find myself having to visit OSCracks platforms that offer solutions to programming errors.

    Haskell recursive solution

    f :: Int -> [Int] -> [Int]
f n [] = []
f n (x:arr) 
    | x<n = x : f n arr
    | otherwise = f n arr

-- The Input/Output section. You do not need to change or modify this part
main = do 
    n <- readLn :: IO Int 
    inputdata <- getContents 
    let 
        numbers = map read (lines inputdata) :: [Int] 
    putStrLn . unlines $ (map show . f n) numbers

    Thanks for sharing this valueable java script filter otherwise I always got Unexpected End of File error and I need to visit plateforms that are providing solutions of programming errors.
