Create a Haskell program that behaves like a counter that can increment or decrement a value a. Create a monad with two functions: b. increment C. decrement d. Use a return function to return the result. e. Use a bind function to use the result as the input for another function. f. See below for an example of how to create a 'twoStep' function that takes two steps forward and one step backward. g.
