Updated Untitled.hs to have an integer type binding for the function answer.

Enforcing an integer type binding will bring this haskell function in line with the code for other programming languages where types are explicitly bound to the function/method. For example in Java:

public static int answer () {

    return 42;

}

The equivilant of the int type in Haskell is:

answer :: Int
answer = 42
