Write a function find_equivalent_matchings that takes a matching and returns all matchings with the same pattern (including the original one).Using this function, draw all matchings equivalent to {(0, 7), (1, 4), (2, 3), (5, 6)}.You might find it helpful to generate all permutations of a list using itertools.permutation (imported above) as in the following code template.perms=permutations (list_of_items)for p in perms: There is a different way of looking at arc diagrams. Let us fix the start and end points of the arcs. We can then ask ourselves how many arc diagrams there are that havethe same pattern of start and end points.For example, if n = 2 and arcs start at 0, 1 and end at 2, 3, we find two arc diagrams which share this pattern.{(1, 2), (0, 3)}1 nesting, O crossings{(0, 2), (1, 3)}O nestings, 1 crossing

Implement a list of employees using a dynamic array of strings.Your solution should include functions for printing list, inserting and removingemployees, and sorting lists (use Bubble sort in C++ language).Keep list of employees sorted within the list after insertion.See the following example:How many employees do you expect to have?5 (Carriage Return)Menu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit2 (Carriage Return)Input name of new employee : MikeMenu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit1(Carriage Return)1 . MaryMenu :1 . Print full list of employees2 . Insert new employee3 . Remove employee from list0 . Exit
Write a function called rem_duplicate that takes a tuple in the parameter and return a tuple removing all the duplicate values. Then print the returned tuple in the function call. Hints: Unlike lists, tuples are immutable so, the tuple taken as an argument cannot be modified. But list can be modified and lastly for returning the result use type conversion. You need to use membership operators (in, not in) for preventing adding any duplicates values. Example1: Function Call: rem_duplicate((1,1,1,2,3,4,5,6,6,6,6,4,0,0,0)) Output: (1, 2, 3, 4, 5, 6, 0) %3D %3D %3D %3D %3D %3D %3D %3D II %3D %3D %3D %3D %3D %3D %3D %3D %3D %3D %3D %3D %3D %3D %3D II %3D %3D %3D %3D I3D %3D I3D %3D %3D
You are going to implement a program that creates an unsorted list by using a linked list implemented by yourself. NOT allowed to use LinkedList class or any other classes that offers list functions. It is REQUIRED to use an ItemType class and a NodeType struct to solve this homework. The “data.txt” file has three lines of data 100, 110, 120, 130, 140, 150, 160 100, 130, 160 1@0, 2@3, 3@END You need to 1. create an empty unsorted list 2. add the numbers from the first line to list using putItem() function. Then print all the current keys to command line in one line using printAll(). 3. delete the numbers given by the second line in the list by using deleteItem() function. Then print all the current keys to command line in one line using printAll().. 4. putItem () the numbers in the third line of the data file to the corresponding location in the list. For example, 1@0 means adding number 1 at position 0 of the list. Then print all the current keys to command line in one…
Using JavaScriptDefine a function getMonth which accepts number from 1 to 12 as an argument and return the descriptive name of the month. For example: getMonth(1) should return January while getMonth(12) returns December, finally getMonth(-1) returns null. Use array or object to define a list of names for the month and refrain from using if statement to check the argument if it's 1, 2, etc.
this code should be in python: write a function that receives a list as its only parameter. Inside the function remove all the duplicate items from the list and returns a new list. For Example: If we call the function with [“dad”, “aunt”, “mom”, “sister”, “mom”] as its input, the returned value should be [“dad”, “aunt”, “mom”, “sister”]. The order of the items inside the returned list does not matter.
Write a function convert_to_millimetres(measurements) which takes a list of measurements in centimetres as a parameter and modifies that list by replacing each measurement with its millimetres version, which involves multiplying by 10. You will need to use the updated-list pattern. (Note that there's no need to return anything because the function modifies the original list it was given.) For example: Test Result measurements = [10.0, 25.0, 1.0] [30.0, 75.0, 3.0] convert_to_millimetres (measurements) print (measurements) Answer: (penalty regime: 0, 10, ... %) 1def convert_to_millimetres(measurements): for i in range(len(measurements)): measurements[i] = measurements[i] * 10 return measurements 3 6 measurements = [10.0, 25.0, 1.0] 8 convert_to_millimetres(measurements) 9 print(measurements) Precheck Check Test Expected Got [30.0, 75.0, 3.0] [100.0, 250.0, 10.0] x [100.0, 250.0, 10.0] measurements = [10.0, 25.0, 1.0] convert_to_millimetres(measurements) print (measurements) Some hidden…

Write a function template that gets an array of generic type T as well as the number of items within the array, calculates the standard deviation of the items within the array and returns it. The user will first give an integerItemCount value (int) and that many integer values (all ints). Then, the user will give a doubleItemCount value (int) and that many double values (all doubles). Then, the program will use the function template to calculate the standard deviations of both arrays and print them out as first the standard deviation of the int array, then the standard deviation of the double array. Standard deviation of an array with size N, values are given as , and arithmetic mean as μ can be calculated as: Requirements: You MUST define and use a function template that takes an array of generic type T and an integer which defines the size of the array Getting all the user input, calling the appropriate version of the function via the template and printing the output should be done…
Write a program that create a class arrayTypeList in which declare a function minimum that return the smallest element of the list. Also, write the definition of the function minimum and a program to test this function.
Write a function countRange() that takes three parameters, a list and two numbers, finds and returns the number of elements that are between the two numbers (both inclusive).Assume that the list contain numbers and the second parameter is less than the third parameter. use=pyhton pls ? and fast answer
Write a function getOdds() that takes a list of integer numbers as parameter, returns a new list made of only the odd numbers in the list.Example: If the parameter list contains [44, 81, 7, 24], the function will return [81, 7].
Write a function getMultiples() that takes a list of integer numbers and an integer number as parameters, returns a new list made of the numbers in the list that are multiples of the number in the second parameter.Example: If the parameters are [44, 80, 72, 245, 7, 24] and 5, then the function will return [80, 245] which are multiples of 5 (or divisible by 5).The function must work for all integer lists and all 2nd integer parameters. pls pyhton and answer fast thank u
