Now create a generic class PersonSet that has one attribute that is a TeeSet of generic type T. Your class must have a default constructor that initializes the TreeSet and another constructor that takes as a parameter List list and uses the list to create the TreeSet with the values of list. It also has a toString() method. In addition, your class must have: • add (T t): adds the element t in the set • remove (T t): removes the element t from the set • T getMax(): returns the maximum object • T getMin(): returns the minimum object • Double getAverage(): returns the average age of the set
CHALLENGE ACTIVITY 6.6.1: Function stubs: Statistics. Define stubs for the functions get_user_num() and compute_avg(). Each stub should print "FIXME: Finish function_name()" followed by a newline, and should return -1. Each stub must also contain the function's parameters.Sample output with two calls to get_user_num() and one call to compute_avg():FIXME: Finish get_user_num() FIXME: Finish get_user_num() FIXME: Finish compute_avg() Avg: -1 Use Python, please.

2.1 Hashing With ChainingWe search/insert/delete in a hashtable in the following way. First use the getHashValue methodto get the hash value. Now use this hash value to get hold of a hash table entry, which is a linkedlist. These functions have been written and you do not need to modify them:• gethashValue: Uses the hash function (37 ∗ val + 61)%T ABLE SIZE.• getList: The hashtable is an array of linked list. So, this method simply returns the linkedlist at a particular index of the hash table. We will use the inbuilt linked-list of C++ or Java. This is an implementation of a doubly-linked-list (with links going both forward and backward). It supports all the standard operations (inserting at front or end, deleting head or tail, traversing the list, etc.) In the next sections (Java), I’ll highlight some of the usages (not all may be required). Since we will deal with integers,I will only discuss integer linked lists, but lists of any type can be created. 2.3 Java• Syntax to create an…
: Implement a CircularArray class that supports an array-like data structure whichcan be efficiently rotated. If possible, the class should use a generic type (also called a template), andshould support iteration via the standard for (Obj o : circularArray) notation.

You have to tick on all possible answers for you to get the points allotted for this question. ab aab bab aaab ba Suppose V = {(0, 1). Using singleton set notations and the operators U, ., and %3D * if appropriate, which expression represents all the elements of V* that has 010 as a substring?

Define a function count_outlier that • accepts an argument myset of type set, and here we assume values in myset are all numerical numbers; cout_outlier (myset) returns the number of values which are not fibonacci numbers in myset. For example: Test assert count_outlier({0, 1, 2, 3, 5, 8)) == 0 assert count_outlier ((13, 144, 99, 76, 1000)) = 3 Result
Directions: Use the set- roaster notation to write the following sets, and determine the number of elements that are in a set. 1. Let A={ 1,2,3 }, B={ 3,1,2 },and C={ 1,1,2,3,3,3 }. What are the elements of A? B? and C? How are A, B and C related? 2. Let A={ w,x,y,z } and B= { a,b }. Find AxB? And BxB?
The last one is RESIGN INACCURACIES this relates to the type of machine or the process used during printing; the printers have a low tolerance meaning that the final product or parts after printing looks different from the original design. It could be fixed but this will increase the time and cost of production.
1. Write linked list classes (one class for Node and another class for List), which store the items in the transaction. 2. Test the classes by printing the items in the linked list 3. Show the total price of the transaction. 4. Delete an item from the linked list and show new output (total price of the transaction).
