Consider the list 1=[3,2,1]. We can use this list to construct a polynomial p by taking the coefficient of the x“ term in p(x) to be equal to 1[n] : p(x) = x² + 2x +3 Implement this idea by writing a function poly_builder (1) that accepts a list 1 and returns a lambda function of a variable x which computes the polynomial with the coefficient of the x" term given by the value 1[n].

Please write a function PythQuad(n) in python that generates a list of pythagorean quadruples (x,y,z,w) such that x <= y <= z <= w < n. A pythagorean quadruple states that x^2 + y^2 + z^2 = w^2. Please do not use a triply nested loop, use the properties of a pythagorean quadruple to write the function.
Finally, we will do some simple analysis – ranking of words. Write a function word_ranking(corpus, n, sort_index) which takes input parameters corpus (type list), n (type int), and sort_index (type int) and returns a list containing tuples of words and their frequencies in the top n of words. Here, corpus is a list of sentences. n is the number of ranked words to return. The resulting list should then be sorted based on the sort_index; sort_index = 0 should sort the list of tuples in ascending alphabetical order, while sort_index = 1 should sort the list of tuples by the frequencies in descending order. All other numeric values for sort_index should return an empty list (don't need to consider non-integer inputs). For example, we have: corpus = ['hi hi hi hi', 'hello hello say bye', 'bye bye']n = 3sort_index = 1 The function should return: [('hi', 4), ('bye', 3), ('hello', 2)] While sort_index = 0 should return: [('bye', 3), ('hello', 2), ('hi', 4)] You can assume n would…
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 order
Does it hold for lists? :Write a function holds_for_lists : ’a list -> ’b list -> (’a -> ’b -> bool) -> bool = that takes an ’a list, an ’b list, a function f: ’ a -> ’b ->bool and returns true if and only if • The two list are of the same length, and • (f a b) is true for all pairs a, b such that a is from the first list, b is from the second list, and a and b appear in the same position in their lists.

Question 2: Write a function that takes a list of distinct integers l, and an integer k. Your function then finds the index of the integer in l, whose removal from l results in a list whose sum is k. For example, given [3,6,4,1,5,2] and 18, your function should return index 0, which corresponds to 3 in the list. Because, when 3 is removed from the list, the sum of the remaining list [6,4,1,5,2] is 18. You can assume that the given problem is always solvable. """ def removeOne(l, k):
1. A triple (x,y,z) of positive integers is called pythagorean if x^2 + y^2 = z^2. Using a list comprehension, define a function: pyths Int -> [(Int, Int, Int)] that maps an integer n to all such triples with components in [1..n]. For example: > pyths 5 [(3,4,5),(4,3,5)]
Define a function prefiaSum which takes a list of numbers as its argument and returns a list of sums of all prefixes of the list. For example: • prefixSum [1..10] => [1,3,6,10,15,21,28,36,45,55] prefixSum [2, 5]=> [2,7]
Define a Haskell function filterTriples that, given a list of integer triples, removes those that are not in ascending order of size. Use list comprehension to implement the function. Example: filterTriples [(1,2,3), (6,5,4), (7,7,7)] ↝ [(1,2,3), (7,7,
2. Write a function that multiplies a polynomial by a constant (or scalar). scale :: (Num a, Eq a) => a -> Poly a -> Poly a For example: > scale 2 (P [-1,0,1]) P [-2,0,2] > scale e (P [0,0,2]) P[]
Exercise 4 Define a function repeats of type 'a list -> bool so that repeats (L) is true if and only if the list L has two equal elements next to each other.
