In Haskell: Write a function which converts a string of digits into an int. you will need the following predefined function: ord 1 --> 49 first char in arg to its ascii code follow the following "pipeline" analysis when defining your function: "167" --> ['1','6','7'] --> [49,54,55] --> [1,6,7] --> [(1,100),(6,10),(7,1)] --> [100, 60, 7] --> 167 (hint: the first function in the pipeline is very simple. why?)
