Given a singly linked list consisting of N nodes. The task is to remove duplicates (nodes with duplicate values) from the given list (if exists). Note: Try not to use extra space. Expected time complexity is O(N). The nodes are arranged in a sorted way. Input:First line of input contains number of testcases T. For each testcase, first line of input contains length of linked list and next line contains the linked list data. Output:For each testcase, there will be a single line of output which contains linked list with no duplicates. User Task: The task is to complete the function remove Duplicates() which should remove the duplicates from linked list. The printing is done automatically by the driver code. Constraints:1 <= T <= 1001 <= N <= 100

Let A and B be two integers valued arrays of sizes n1 & n2 respectively. The elements of the two arrays are sorted in increasing order and may contain duplicate elements.It is required to form a list, C, of distinct elements, in increasing order, that are in A but not in B and in B but not in A. (There shall be no duplicate elements in list C.)The two arrays, A & B, can only be traversed once.Example:A: -2, 2, 4, 4, 4, 7, 9, 9, 9, 12, 15,B: 1, 2, 5, 9, 15, 15, 15, 17, 17, 17C: -2, 1, 4, 5, 7, 12, 17
Given pointers to the head nodes of linked lists that merge together at some point, find the node where the two lists merge. The merge point is where both lists point to the same node, i.e. they reference the same memory location. It is guaranteed that the two head nodes will be different, and neither will be NULL. If the lists share a common node, return that node's value. Note: After the merge point, both lists will share the same node pointers. Example In the diagram below, the two lists converge at Node x: [List #1] a--->b--->c \ x--->y--->z--->NULL / [List #2] p--->q Function Description Complete the findMergeNode function in the editor below. findMergeNode has the following parameters: SinglyLinkedListNode pointer head1: a reference to the head of the first list SinglyLinkedListNode pointer head2: a reference to the head of the second list Returns int: the value of the node where the lists merge Input Format Do not read any input from…
Given two lists sorted in increasing order, create and return a merged list of all the elements in sorted order. You may modify the passed in lists. Ideally, the solution should work in "linear" time, making a single pass through each list.
For this exercise, a list of non-negative numbers will be given, for which the following operation can be done: subtract 1 from two contiguous elements from the list. It must say whether after any number of operations the list can be converted to a list of zeros. EntryThe input will be a list of non-negative integers x_i such that 0 <= x_i <= 2000000000. ". DepartureIf the given list can be converted to a list of zeros with the operation defined above, print "YES", otherwise, print "NO". Examples Input Example 1 1 2Output Example 1 NOT Input Example 2 2 4 2Output Example 2 YES
Given an array of 1000 integers: a. In the best-case scenario, what is the fewest possible comparisons needed to find a number using linear search? b. In the worst-case scenario, what is the most number of comparisons needed to find a number using linear search? c. How many comparisons will be done if we attempt to search for a number that does not exist in the list using linear search?
The special case(s) when deleting a node in a linked list is/are: а. The list is empty. O b. All c. The node to be deleted is the first node. O d. There is only one node in the list.
Exercise 3D Write a function sundaram which implements this algorithm. You should check the results by comparing the final list to that produced by the sieve of Eratosthenes, and for the avoidance of doubt, the output of sundaram (5) should be [ 3,5,7,11].
WRITE THE MAIN.CPP FOR THIS PROGRAM a. Write a version of the sequential search algorithm that can be used to search a sorted list. (1, 2) b. Consider the following list: 2, 20, 38, 41, 49, 56, 62, 70, 88, 95, 100, 135, 145 Using a sequential search on ordered lists, that you designed in (a), how many comparisons are required to determine whether the following items are in the list? (Recall that comparisons mean item comparisons, not index comparisons.) (1, 2) 2 57 88 70 135 Write a program to test the function you designed. Note: Have the function,seqOrdSearch, return -1 if the item is not found in the list. (return the index of the item if found).
Assume that the values A through H are stored in a self-organizing list, initially in ascending order. Using the move-to-front heuristic and the table below, show the resulting list from the following series of accesses (note -- you only have to show the values in the last column of the table below): G H G H E C E H G A D C F Inputs List at Start G H G H E C E H G A D C F A B C D E F G H
Given a singly linked list L, where x and y are two data elements that occupy the nodes NODEX and NODEY with PREVIOUSX as the node, which is the previous node of NODEX, write a pseudo-code to swap the date x and y in list L by manipulating the links only (data swapping is not allowed). Assume that x and y are available in the list and are neither neighbors nor the end nodes of list L. For example, given the list L shown in Figure P6.10(a), with L, NODEX, NODEY and PREVIOUSX marked on it, the swapping should yield the list shown in Figure P6.10(b). NODEX and NODEY are neither immediate neighbors nor the end nodes of list L.

For a linked version of insertion sort, since there is no movement of data, thereis no need to start searching at the end of the sorted sublist. Instead, we shalltraverse the original list, taking one entry at a time and inserting it in the properposition in the sorted list. The pointer variable last_sorted will reference the end ofalgorithm the sorted part of the list, and last_sorted->next will reference the first entry thathas not yet been inserted into the sorted sublist. We shall let first_unsorted alsopoint to this entry and use a pointer current to search the sorted part of the list tofind where to insert *first_unsorted. If *first_unsorted belongs before the currenthead of the list, then we insert it there. Otherwise, we move current down thelist until first_unsorted->entry <= current->entry and then insert *first_unsortedbefore *current. To enable insertion before *current we keep a second pointertrailing in lock step one position closer to the head than current.…
