I translated from Haskell lol

In Haskell the length of list is not always 10:

import Debug.Trace

points :: [String] -> Int
points x = trace (show x) undefined

Random tests:

uncaught exception: ErrorCall (Prelude.undefined
CallStack (from HasCallStack):
  error, called at libraries/base/GHC/Err.hs:79:14 in base:GHC.Err
  undefined, called at src/TotalPoints.hs:34:27 in main:TotalPoints) (after 1 test)
*** Failed! (after 1 test): 
Exception:
  Prelude.undefined
  CallStack (from HasCallStack):
    error, called at libraries/base/GHC/Err.hs:79:14 in base:GHC.Err
    undefined, called at src/TotalPoints.hs:34:27 in main:TotalPoints
[3,0]
[]

STDERR:

["1:0","2:0","3:0","4:0","2:1","3:1","4:1","3:2","4:2","4:3"]
[]

Me too. My code passed all the tests but exited with Exit Code: 255. I am using Haskell.

I found my solution by searching for the sequence on OEIS :)

C++ Translation

Please review and approve.

Still remember I could not understand this code several months ago :D

There have already been an (&) function in Data.Function that do the same thing like (|>), so we could just write

infixl 0 |>
(|>) = (&)

If you are using a language with lazy evaluation like Haskell then this is the best practice :-)
