Because floating-point numbers are imprecise, it is common to compute data values of type float that are very close but not exactly equal to the value 0.0. a) In Python, Write a function countNZdata that counts number of elements in a list of type float whose absolute value is less than or equal to a positive tolerance parameter. The function takes the list as its first parameter; the second parameter is the positive float value that is the tolerance. Function should return the number of data values that meet this criterion. For example, for the given list: [2.19, -0.04, 1.66, 0.05, 4.70, -6.53, -0.11, -1.07, 1.94, -2.23] and a tolerance = 0.1, the function should return the value 3. b) Demonstrate that the function works by inputting different example values.

Algorithm Efficiency 1- Programming Problem Part 1 Write a function that will have a list as an input, the task of the function is to check if all the elements in the list are unique,( i.e. no repetition of any value has occurred in the list), then the function returns true otherwise it returns false. Your program should include a main method that call the method to test it. (If you would use built-in functions in Python, use lists’ or dictionaries’ methods as we studied their time efficiency in class) 2- Algorithm AnalysisFor the function you implemented in part 1, please calculate T(n), which represents the running time of your algorithm in terms of n. Where n is the length of the list. Then find the order of magnitude of your algorithm (Big O). 3- Algorithms Comparison Please find another algorithm that solves part 1, write the code, calculate T(n) and find Big O. Then compare the efficiency with the algorithm from part1 to determine the more efficient one.
Code in python Given a list, L, the function front_two creates a new list of length 2 out of the first two items in L as follows: In the new list, the second item becomes the first item, and the first item becomes the second. If L contains only one item, the first item in the new list should be the value None. If L is empty, both items in the new list should be value None. The function returns the new list. For example: Test Result L = ['a', 'b', 'c', 'd'] print(front_two(L)) ['b', 'a'] L = [] print(front_two(L)) [None, None] L = [5, 2] print(front_two(L)) [2, 5] L = [7] print(front_two(L)) [None, 7]

Exercise, maxCylinderVolume F# system function such as min or methods in the list module such as List.map are not allowed Write a function maxCylinderVolume that takes a list of floating-point tuples that represent dimensions of a cylinder and returns the volume of the cylinder that has the largest volume. Each tuple has two floating point values that are both greater than zero. The first value is the radius r and the second value is the height h. The volume of the cylinder is computed using ??2h. The value π is represented in F# with System.Math.PI. If the list is empty, return 0.0. Examples: > maxCylinderVolume [(2.1, 3.4); (4.7, 2.8); (0.9, 6.1); (3.2, 5.4)];;val it : float = 194.3137888> maxCylinderVolume [(0.33, 0.66)];;val it : float = 0.2257988304
python exercise: 1. Write a Python function called generate_quiz_question that takes a list of quiz questions (represented as tuples of the question and answer) as input and returns a randomly selected question from the list. The function should also prompt the user to enter their answer to the question, and then check whether the user's answer is correct or not. If the user's answer is correct, the function should return True. Otherwise, it should return False. 2. Write a function is_palindrome(s) that takes a string s as input and returns True if s is a palindrome (i.e., reads the same backwards and forwards), and False otherwise 3. Write a Python function called get_top_students that takes the list of dictionaries as input and returns a dictionary containing the name and GPA of the top two students in the list. Each dictionary has the following keys: "name", "age", "major", and "gpa".

PYTHON CS1 PROBLEM Define a function that takes a list of lists, glol, as a parameter. You may assume that the inner lists in glol are lists of positive integers. Your function should return True if at least one of the inner lists in glol contains two or more multiples of 10. Otherwise it should return False. For example: If glol = [ ] then your function returns False. If glol = [[ ], [4, 2]] then your function returns False. If glol = [[10, 2, 6, 8], [12, 6], [15, 20, 5]] then your function returns False. If glol = [[10, 2, 6], [12, 6], [10, 2, 70, 15], [15, 10, 5]] then your function returns True as the inner list [10, 2, 70, 15] contains 10 and 70. If glol = [[10, 2, 6], [12, 6], [10, 7, 15], [50, 10, 50, 4, 6]] then your function returns True as the inner list [50, 10, 50, 4, 6] contains 50 twice. 6. If glol = [[10, 20, 6, 90], [12, 6], [ 7, 3, 15], [50, 10, 50, 4, 7]] then your function returns True as the inner lists [50, 10, 50, 4, 7] and [10, 20, 6, 90] contain more…

please code in python A mining company conducts a survey of an n-by-n square grid of land. Each row of land is numbered from 0 to n-1 where 0 is the top and n-1 is the bottom, and each column is also numbered from 0 to n-1 where 0 is the left and n-1 is the right. The company wishes to record which squares of this grid contain mineral deposits. The company decides to use a list of tuples to store the location of each deposit. The first item in each tuple is the row of the deposit. The second item is the column. The third item is a non-negative number representing the size of the deposit, in tons. For example, the following code defines a sample representation of a set of deposits in an 8-by-8 grid.deposits = [(0, 4, .3), (6, 2, 3), (3, 7, 2.2), (5, 5, .5), (3, 5, .8), (7, 7, .3)]Given a list of deposits like the one above, write a function to create a string representation for a rectangular sub-region of the land. Your function should take a list of deposits, then a set of parameters…
