Solved in 3 steps with 1 images
- Remember that an integer n is prime if (i) n> 2 and (ii) it is only divisible by 1 and n itself. Subtask I: You will start by implementing a function is_prime(n: int) -> bool that returns True if the number n is prime and False otherwise. For example: • is_prime(1) should return False. is_prime(2) should return True. is_prime(-2) should return False. is_prime(5) should return True. • is_prime(41) should return True. • is_prime(323) should return False. Subtask II: The thing is, many people believe prime numbers bring sadness and must be avoided. To this end, you'll write a function sans_primes(numbers: list[int]) -> list[int] that takes in a list of integers and returns the numbers in the input list in the original order, except that every prime number is banned, so it will be excluded and numbers that come immediately after a prime number will also be excluded. For example: • sans_primes([1, 4, 9, 10]) should return [1, 4, 9, 10]. • sans_primes([1, 11, 9, 10, 17]) should return [1,…I need this answer in Haskell Programming language only. 4. Write a function that adds two polynomials. Ensure that the polynomial produced matches the requirements. addPoly :: (Num a, Eq a) => Poly a -> Poly a -> Poly a For example: > addPoly (P [1]) (P [-1,1])P [0,1]> addPoly (P [17]) (P [0,0,0,1])P [17,0,0,1]>addPoly (P [1,-1]) (P [0,1])P [1] You may find it helpful to write addPoly using two helper functions: one to combine the lists of coefficients, and one to trim trailing zeroes. Your implementation of addPoly should have this property: addPoly p q $$ x == (p $$ x) + (q $$ x)Correct and detailed answer will be Upvoted In C Question: How can the function, matrix_initialize_unopt, be optimized and rewritten with loop collapsing? n has a size of 3000 struct fn_args { int n; int *mem1; int *mem2; }; int check(int x, int y) { return x < y; } void set(int *mat, int i, int num) { mat[i] = num; } void matrix_initialize_unopt(struct fn_args *args) { int i, j, n; int *mat1, *mat2; n = args->n; mat1 = args->mem1; mat2 = args->mem2; for (i = 0; check(i, n); i++){ for (j = 0; check(j, n); j++){ set(mat1, i * n + j, i); set(mat2, i * n + j, i+1); } } }

The cut takes the first card off the deck and places it face down, then takes the second card and places it face down on top of the first, and this continues up until and including the mth card. The remainder of the deck, n – m cards, is simply placed on top of the deck of face-down cards. function deck_1(n, m) { // Your code goes here // Return the new location of the // last card which was at offset n-1 return 0; } INPUT: n and m where [n/2] < mmachine learning coding in PythonTask 1. Area between two curves Consider the graphs of the functions f(x) = m-x and g(x) = 2x². - n where m and n are the maximum and mean values of the digits in your student-ID number. student-ID number=201904598 a) Create a vector v whose elements are the digits of your student-ID number. b) Create a variable m and assign the maximum digit in v to it. c) Create a variable n and assign the mean value of the digits in v to it. d) Define the function f(x) and g(x) above as anonymous functions. e) Plot the graphs of f(x) and g(x) on the same figure using the MATLAB function ezplot. f) Find the exact values of the x-coordinates of the intersection points between the two graphs using the MATLAB function solve. g) Find the area bounded by the two graphs.Which of the following is the definition of a higher-order function? func xs = sum (map (^2) xs) func x = x * 2 func (x,y) = (y,x) func (x:y:zs) = y func f [x,y] = [f x, f y]For input vector x, write a function to check whether there exists at most 5 elements in x whose values are less than 7.Change two lines of code of: def solution(A, K): n = len(A) for i in range(n - 1): if (A[i] + 1 < A[i + 1]): return False if (A[0] != 1 and A[n - 1] != K): return False else: return True SO that it solves the question : you are given a implementation of a function def solution (A,K) This function, given a non-empty array A of N integers (sorted in non-decreasing order) and integer K, checks whether A contains numbers 1,2..K (every numbers from 1 to K at least once and no other numbers (for example given array A, K=3 ; A(0)=1, A(1)=1, A(2)=2, A(3)=3, A(4)=3 then the function should return True while for the following array A, K=2; A(0)=1, A(1)=1, A(2)=3 then the function should return False.) Assume that: -N and K are integers within the range (1....300,000) -each element of array A is an integer within the range (0...1,000,000,000) -array A is sorted in non-decreasing orderA university assigns student IDs of the form 1, 2, 3, ... such that if n students are currently enrolled, then the next student to enroll will receive and ID of n + 1. Consider the following algorithm that accomplishes this. // Global variable storing number of students currently enrolled current_student_count = 0 // Function that reads the above global variable, calculates new ID, and increments the global count assign_new_id(): count = current_student_count new_id = count + 1 current_student_count = count + 1 return new_id (a) If two different threads run the above code in parallel to enroll two different students, it is possible for the two students to receive the same ID, and for the current_student_count to have a wrong value. Explain how this is possible. (b) Modify the code above so that the problem in (a) does not happen.SEE MORE QUESTIONS
