- detemine if the follow statement are true or False and why? screenshots show the ArrayBoundedStack class and StackUnderflowException code If N represents the number of elements on the stack, then the push method of the ArrayBoundedStack class is O(N). While processing this expression ( } ( ) ( ) { { { } [ ] } } ) the highest number of elements on our stack at any one time is 1. If N represents the maximum possible number of elements on the stack, then the ArrayBasedStack constructor is O(N). The following expression is balanced: ( ( ( [ ) ] ) ) Our StackUnderflowException code essentially consists of two simple constructors and "packages" and "extends" statements and nothing else.Question 1 If N represents the number of elements in the collection, then the add method of the SortedArrayCollection class is O(N). True False Question 2 If N represents the number of elements in the list, then the index-based remove method of the ABList class is O(N). True False Question 3 The add method of our Collection ADT might throw the CollectionOverflowException. True False Question 4 A list allows retrieval of information based on the size of the information. True False Question 5 Our CollectionInterface defines a single constructor. True False Question 6 Our lists allow null elements. True False Question 7 Even though our collections will be generic, our CollectionInterface is not generic. True False Question 8 Our lists are unbounded. True False Question 9 If N represents the number of elements in the collection, then the contains method of the ArrayCollection class is O(N). True False Question 10 Our lists allow duplicate elements. True FalseSuppose myList is an object of List data structure, and myList.displayList() produces the following output: 18 17 16 28 70 What would be the output when the following statements are executed? myList.InsertNode(3, 10); myList.DisplayList(); Select one: A.18 10 17 16 28 70 B.18 17 10 16 28 70 C.18 17 16 10 28 70 D.18 17 16 28 10 70
- 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…Considering all the elements and its indexes at the right side:Write a sequence of List operations that would result to a LIST that contains ONLY the elements with its respective indexes: {index[00]=104, index[01]=165, index[02]=115, index[03]=384, index[04]=248, index[05]=117}.How much memory is needed to store an Array than a linked list. a. Equal b. Less c. More d. None of the above
- Create a Numpy List named as marks with six float numbers, showing the final marks of a student in six subjects. Round the marks from marks array from Q-3 a) up to two decimal numbers What if you need to create the same list as Q-3 a), but for five students. Can you still use 1-D array? How many dimensions should be there? Find the highest marks a student has obtained using marks array from Q-3 a) Use seaborn to show marks array from Q-3 a)you are given a variable zipcode_list that contains a list. Write some code that assigns True to the variable duplicates if the there are two adjacent elements in the list that have the same value, but that otherwise assigns False to duplicates otherwise. use only variables k, zipcode_list, and duplicatesA) Given a list, iterate it, and display numbers divisible by five, and if you find a number greater than 150, stop the loop iterations list = [12,15,32,42,55,75,122,132,150,180,200]
- ????????: Consider this following dictionary of lists for your question. So just copy this dictionary to your editor. number_lists = {1: [2,6,4], 2: [51,6,89], 3: [23,9,32], 4: [31,53,8], 5: [7,44,55]} Take an integer from the user (The number should be greater than 0), add up all the digits. If the summation of all the digits is even then find the summation of all the even values of all the odd keys from the given dictionary. If the summation is odd then find the summation of all the odd values of all the even keys from the given dictionary. Then print the summation. Sample Input 1: 441 Sample Output 1: 224 Explanation 01: The summation of digits of given input is 4+4+1 = 9 which is an odd number. That’s why we need to find the even keys from the dictionary which are {2: [51,6,89], 4: [31,53,8] } and sum up the odd values from these even keys which results in 51+89+31+53 = 224.
