True/False 3. Arrays are usually heterogeneous, but lists are homogeneous.
Which of the following statements regarding linked lists and arrays is correct? Group of answer choices: a. A dynamically resizable array makes insertions at the beginning of an array very efficient. b. Using a doubly linked list is more efficient than an array when accessing the ith element of a structure. c. A dynamically resizable array is another name for a linked list. d. Any type of list tends to be better than an array when there are a set number of maximum items known beforehand. e. If many deletions at any place in the structure were common, a linked list implementation would likely be preferable to an array
25. Minimum Difference Sum Given an array of n integers, rearrange them so that the sum of the absolute differences of all adjacent elements is minimized. Then, compute the sum of those absolute differences. Example n = 5 arr = [1, 3, 3, 2, 4] If the list is rearranged as arr' = [1, 2, 3, 3, 4], the absolute differences are /1-2/ = 1, 12-3|= 1, 13- 3|=0, 13-4/= 1. The sum of those differences is 1+1+0+1 = 3.

D.List Access a singe element of the structure by referring to its position in the structure. v Access a sirngle clement of the structure by referring to an index value. All elements in the structure must share a single data type (integer, fiaat, string, etr.
Consider the following linked list of the form. This list already exists, so you do not need to write the code to create the list below: struct nodeType { int infoData; nodeType * next; }; nodeType *first; … and containing the values: first (( See image for values )) Use this linked list to perform the following actions. Declare any additional pointers, etc., if needed, to complete the code. You do not need to write any includes or using statements—just program segments. Write a code segment that creates a new node with infoData = 13 and inserts the node after the node with the value 12.
Part 1: Array list implementation: array list implements list interface plus their own functions. 1. a. Create a ArrayList of type Integer and name it as Grades. b. Create a ArrayList of type String and name it as Students. c. Create a ArrayList of type Double and name it as Results. 2. Add the following values to the array List using add function 30, 40,80 ,100,70,100,10,100,10 Print the size of the array list using size () function. 3.Search for 100 in the array list, if you find it, print a message that “those grades are perfect”. Use only contains function. 4. Repeat the step 3 using equals function. 5. Check if array list is empty or not using isEmpty() function. Print a message if it’s empty and if it’s not empty also. 6. the grade is under 20 which is outlier, remove it from the array list. 7. Print array list using System.out.println() 8. Use indexOf to print index of 80. 9. Use get function. 10. What is the difference between get and index of? 11. Print the values of the array…
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
If N represents the number of elements in the collection, then the contains method of the ArrayCollection class is O(1). True or False If N represents the number of elements in the list, then the index-based add method of the ABList class is O(N). True or False
Write a function with below starting function: public static void printFirstAnd Last(ArrayList list) The approach should accomplish the following: Print "no elements" if the list is empty. Print the single element in the list if there is only one. Print the first entry in a list with more than one element, followed by a space, and then the last element.
PART A. We will start by finding the largest value. Initially, we assume that the first element in the list is the largest element and create a variable maxValue that is initialized to the first element in the array. We then compare the element that maxValue is storing with every element in the list. Whenever we find an element in the array larger than the element that maxValue is storing, we update maxValue so that it stores the value of the newer larger element. Algorithm ArrayLargestElement Declare and initialize maxValue to the first element in the array. Use a FOR loop to traverse the array. // You already checked the first element, so you should start the loop at the second element. If the element at this index is larger than maxValue Update maxValue Output maxValue. Write a program MyArray_ABC that declares an array containing the following elements: 45, 38, 27, 46, 81, 72, 56, 61, 20, 48, 76, 91, 57, 35, and 78, and outputs the largest value. Additionally,…
There are many differences between array and linked list, one of these differences: a. In a linked list insertion and deletion takes more time b. Array supports random access while linked List supports sequential access c. in linked list, elements are stored in contiguous memory location while in array are stored anywhere in the memory d. None of the above
stats.py: We can create a numpy array from separate lists by specifying a format for each field:arr = np.zeros(4, dtype={'names': ('name', 'age', 'major', 'gpa'), 'formats': ('U50', 'i4', 'U4', 'f8')})arr['name'] = ['Alice', 'Bob', 'Carol', 'Dennis']arr['age'] = [21, 25, 18, 29]arr['major'] = ['CS', 'Math', 'Chem', 'Phys']arr['gpa'] = [3.8, 3.2, 4.0, 3.5] where U50 is a string of max length 50, i4 is a 4-byte integer, U4 is a string of max length 4, and f8 is an 8-byte floating-point number. Then arr has value array([('Alice', 21, 'CS', 3.8), ('Bob', 25, 'CS', 3.2),('Carol', 18, 'Chem', 4. ), ('Dennis', 29, 'Phys', 3.5)],dtype=[('name', '<U50'), ('age', '<i4'), ('major', '<U4'), ('gpa', '<f8')]) Then, for example, arr[’name’] will give an array of just the student names.Write a program that reads the file roster2.dat that has this format: name,age,major,gpa Convert this to a numpy array as shown above. Then use that array to compute…
