- How is an array stored in main memory? How is a linked list stored in main memory? What are their comparative advantages and disadvantages? Give examples of data that would be best stored as an array and as a linked list.linked list question Which of the following statements are correct about adding an element to a list implemented using arrays with no maximum limit for the number of elements and array growing? Adding an element may require copying elements to a new array in some cases. The worst-case time complexity of adding an element is O(1)Question1: define two lists of numbers (arrays) and ask the user to give the size of each, and then ask the user to fill the list(according to a size that he gave), then compare two arrays and determine whether they are equal? Note: two arrays are equal if all elements are equal. (Array not vector) C++
- True or False For each statement below, indicate whether you think it is True or False If you have an array with no “holes”, the append function performs at O(1) Inserting an element at the front and shifting all elements performs significantly worse than appending an element at the end of the list For the insert function, if the array is empty, there are no comparison operations that need to be performed and you can immediately add the new element Binary search can be used on an unsorted array to significantly improve its performance from O(n) to O(1)True or False For each statement below, indicate whether you think it is True or False If you have an array with no “holes”, the append function performs at O(1) Inserting an element at the front and shifting all elements performs significantly worse than appending an element at the end of the list For the insert function, if the array is empty, there are no comparison operations that need to be performed and you can immediately add the new element Binary search can be used on an unsorted array to significantly improve its performance from O(n) to O(1) Because the update algorithm depends on using linear search, its performance is O(1) in the worst case scenario True If you search for and delete an element in an unsorted array and then shift the rest of the elements to fill the hole, the worst case performance is O(n) If you search for and delete an element in an unsorted array and then move the last element to fill the hole, the worst case performance is O(n)(Merge two sorted) Write the following function that merges two sorted lists into a new sorted list:void merge(const int list1[], int size1, const int list2[], int size2,int list3[])Implement the function in a way that takes size1 + size2 comparisons. Write a test program thatprompts the user to enter two sorted lists and display the merged list.Here is a sample run.Note that the first number in the input indicates the number of the elements in the list. This number isnot part of the list. Assume the maximum list size is 80.Enter list1: 5 1 5 16 61 111Enter list2: 4 2 4 5 6The merged list is 1 2 4 5 5 6 16 61 111
