Can check if you're using swap with sudo swapon --show and free -h.

EBS volume

Useful for t2.micro and other instances with no access to instance store. Use this if you prefer not to mess with the root volume.

{-
The origin of this puzzle if from #codingame chat. Ideas for the high
level approach come from TheNinja.

Write a program that outputs all possibilities to put + or - or nothing
between the numbers 1,2,...,9 (in this order) such that the result is
equal to stdin. For an example: 1 + 2 + 3 - 4 + 5 + 6 + 78 + 9 = 100.

Usage:

import Data.Char (digitToInt)
import System.IO

main :: IO ()
main = do
    hSetBuffering stdout NoBuffering
    putStrLn $ concatMap toFancy $ sumOfDigits fib

toFancy :: Integer -> String
toFancy x
