Please write below functions in HASKELL programming language.

1. Write a function init' that has identical behavior to the init function. In your definition, you may only use the standard Haskell functions that operate on lists (except for init). init' :: [Int] -> [Int]
2. Write a recursive function init'' that has the same behavior as init'. No standard Haskell functions may be used. init'' :: [Int] -> [Int]
