Problem
Function generate-takes three ints as arguments and generates a list of integers from arg1 to arg2 (inclusive) in increments indicated by arg3, e .g. if arg1 = 3, arg2 = 8, and arg 3 = 2, then the function returns [3, 5, 7]. If arg1> arg2, returns an empty list; assume arg3 will be a valid number; you are NOT allowed to use ++ or built-in functions or list comprehension; add appropriate test cases to the test file.
