The following function is designed to take in a nested list structure of unknown depth, whereeach element at every level is either an integer or a list.

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
In C++ data structure Please write program per instructions. Thank you A set is a collection of distinct elements of the same type. Design the class unorderedSetType, derived from the unorderedArrayListType, to manipulate sets. Note that you need to redefine only the f unctions insertAt, insertEnd, and replaceAt. If the item to be inserted is already in the list, the functions insertAt and insertEnd output an appropriate message. Similarly, if the item to be replaced is already in the list, the function replaceAt outputs and appropriate message. Also, write a program to test your class: then Redo the program using templates
Max Absolute In List Function Lab Description Implement function max_abs_val(lst), which returns the maximum absolutevalue of the elements in list.For example, given a list lst: [-19, -3, 20, -1, 0, -25], the functionshould return 25. The name of the method should be max_abs_val and the method should take one parameter which is the list of values to test. Here is an example call to the function print(max_abs_val([-19, -3, 20, -1, 0, -25])) File Name maxabsinlst.py Score There are three tests each worth 2 points Note: You do not need any other code including the main method or any print statements. ONLY the max_abs_val method is required. Otherwise, the autograder will fail and be unable to grade your code. (I.e., do not include the above example in your code.) The above example should be used be test your code but deleted or comment out upon submission. PYTHON LAB

The mapped list pattern Our second pattern is the mapped list pattern, described in video 4 3 mapped list pattern. Often we need to write a function that takes a list as a parameter and returns a new list in which each item in the original list is "mapped" to a new item in the result list. For example, the following function takes a list of numbers as a parameter and returns a list of all the numbers squared, e.g. squares ( [1, 3, 7]) returns [1, 9, 49]. def squares (nums): "Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result Although this is just a special case of the accumulator pattern, it is so common that we give it its own name: the mapped list pattern. Consider the following function: def squares(nums): ""Returns the squares of the given numbers""" result = [] for num in nums: result.append (num * num) return result If the main program calls print(squares ( [5, -3, 2, 7]) what is the state table for the function…

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…
