### Function Definitions in Haskell and ML**Consider the following three function definitions in Haskell:**```haskellfirst x y = xident x = xomega x = omega x```- `first x y = x`: This function takes two arguments `x` and `y`, and returns `x`.- `ident x = x`: This function takes a single argument `x` and returns `x`.- `omega x = omega x`: This function is recursive and will cause an infinite loop when called, as it is defined in terms of itself with the same argument.**The same functions can also be defined in ML, although with a slightly different syntax:**```mlfun Ident x = x;```- `fun Ident x = x;`: This is equivalent to `ident x = x` in Haskell, taking a single argument `x` and returning `x`.**Comparison of Evaluations in Haskell and ML**Consider the evaluation of the following expression in Haskell and ML:```haskellfirst (ident 3) (omega 1)``````ml{First (Ident 3) (Omega 1). in ML}```- In Haskell: - `ident 3` evaluates to `3` since `ident x = x`. - `omega 1` does not terminate as it initiates an infinite loop (`omega 1 = omega 1`). - `first` takes two arguments but will return the first one without evaluating the second, so `first (ident 3) (omega 1)` will effectively return `3` without getting stuck in the infinite loop caused by `omega 1`.- In ML: - `Ident 3` evaluates to `3`, analogous to Haskell's `ident 3`. - However, `Omega` would initiate an infinite loop in ML just as in Haskell with the `omega` function. - In ML, depending on the language's evaluation strategy, the overall result may differ from Haskell. In strict evaluation (which most ML variants follow), `Omega 1` would be evaluated before being passed into `First`, causing an infinite loop and preventing a result.By comparing these evaluations, one can observe the differences in how Haskell and ML approach function evaluation, particularly in the handling of non-terminating functions and short-circuiting behavior.
