quadrant [★★] Complete the quadrant function below, which should return the quadrant of the given x, y point according to the diagram on the right (borrowed from Wikipedia). Points that lie on an axis do not belong to any quandrant. Hints: (a) define a helper function for the sign of an integer, (b) match against a pair. type quad = I | II | III | IV type sign = Neg | Zero | Pos let sign (x:int) : sign = ... let quadrant : int*int -> quad option = fun (x,y) -> match ... with | ... -> Some I | ... -> Some II | ... -> Some III | ... -> Some IV | ... -> None B) quadrant when [★★] Rewrite the quadrant function to use the when syntax. You won’t need your helper function from before. let quadrant_when : int*int -> quad option = function | ... when ... -> Some I | ... when ... -> Some II | ... when ... -> Some III | ... when ... -> Some IV | ... -> None please use Ocaml for the code

Interesting, intersecting def squares_intersect(s1, s2): A square on the two-dimensional plane can be defined as a tuple (x, y, r) where (x, y) are the coordinates of its bottom left corner and r is the length of the side of the square. Given two squares as tuples (x1, y1, r1) and (x2, y2, r2), this function should determine whether these two squares intersect, that is, their areas have at least one point in common, even if that one point is merely the shared corner point when these two squares are placed kitty corner. This function should not contain any loops or list comprehensions of any kind, but should compute the result using only integer comparisons and conditional statements. This problem showcases an idea that comes up with some problems of this nature; it is actually far easier to determine that the two squares do not intersect, and negate that answer. Two squares do not intersect if one of them ends in the horizontal direction before the other one begins, or if the same…
influence.measures function in R gives you a list. In it, there is a matrix that tells you whether an observation is influential or not. Do research on the cutoff values used by this function and comment on the possible problems that might arise when using built-in functions.

PYTHON Call expressions, such as square(2), apply functions to arguments. When executing call expressions, we create a new frame in our diagram to keep track of local variables: Evaluate the operator, which should evaluate to a function. Evaluate the operands from left to right. Draw a new frame, labeling it with the following: A unique index (f1, f2, f3, ...) The intrinsic name of the function, which is the name of the function object itself.For example, if the function object is func square(x)[parent=Global], the intrinsic name is square. The parent frame ([parent=Global]) Bind the formal parameters to the argument values obtained in step 2 (e.g. bind x to 3). Evaluate the body of the function in this new frame until a return value is obtained. Write down the return value in the frame. If a function does not have a return value, it implicitly returns None. In that case, the “Return value" box should contain None. Let's put it all together! Draw an environment diagram for the…

Restructure Newton's method (Case Study: Approximating Square Roots) by decomposing it into three cooperating functions: newton, limitReached, and improveEstimate. The newton function can use either the recursive strategy of Project 2 or the iterative strategy of the Approximating Square Roots Case Study. The task of testing for the limit is assigned to a function named limitReached, whereas the task of computing a new approximation is assigned to a function named improveEstimate. Each function expects the relevant arguments and returns an appropriate value. An example of the program input and output is shown below: Enter a positive number or enter/return to quit: 2 The program's estimate is 1.4142135623746899 Python's estimate is 1.4142135623730951 Enter a positive number or enter/return

This is to be done in ML coding language. Please provide the actual code, and try to keep the code as simple as possible. Define a function which computes the product of all integers betweenm and n (with n >= m) inclusive. Use this function to define the function Cn,k (thenumber of combinations of n elements taken k by k), which is defined by Cn,k = n!/(k!*(n-k)!) Test your code with sample input and report result.
Hi, OCaml programming 1. Create a type slidingTile, consisting of a char matrix and two integers xand y. The integers x and y are the coordinates of an empty tile. 2. Create a function val slide : slidingTile -> int -> int -> slidingTile = <fun> that given a slidingTile and two integers, that represent a location in thematrix, it slides the tile from the specified location to the empty tile, thenreturns the altered slidingTile. If provided location is not adjacent to theempty tile, or out of bounds, then return the slidingTile unaltered. 3. Create a function val print_tile : slidingTile -> unit = <fun> that prints a slidingTile on screen with the corresponding characters fromthe matrix. However, print an empty space where the empty tile is instead.
Discrete mathematics applied to computer science: homework question. Let f : A → A be a function in the domain A =/= ∅. Confirm or deny, with justification: f is a bijection if and only if the composition f ◦ f is a bijection. I don't understand how I should approach this problem. Thank you for your gracious help.
