Please answer this question and plz don't reject it under complex question Example 13.5Write a function to delete a specified node.A function to delete a specified node is given in Fig.13.9. The function first checks whether thespecified item belongs to the first node. If yes, then the pointer to the second node is temporarilyassigned the pointer variable p, the memory space occupied by the first node is freed and thelocation of the second node is assigned to head. Thus, the previous second node becomes thefirst node of the new list.If the item to be deleted is not the first one, then we use the find function to locate the position of"key node' containing the item to be deleted. The pointers are interchanged with the help of atemporary pointer variable making the pointer in the preceding node to point to the node followingthe key node. The memory space of key node that has been deleted if freed. The figure belowshows the relative position of the key node.key noden1n1->nextn1->next->nextThe execution of the following code deletes the key node.p = n1->next->next;free (n1->next);n1->next = p;n1->nextkey noden1

Python only** define the following function: 1. This function must add a task to a checklist, setting its initial value to False. It will accept two parameters: the checklist object to add to, and the task name to add. In addition to adding the task, it must return the (now modified) checklist object that it was given. There is one issue, however: a task cannot be added to a checklist if the name requested is already being used by another task in that checklist. In that case, this function must print a specific message and must return None Define addTask with 2 parameters Use def to define addTask with 2 parameters Use a return statement Within the definition of addTask with 2 parameters, use return _ in at least one place. Do not use any kind of loop Within the definition of addTask with 2 parameters, do not use any kind of loop.

Pointer arithmetic. Implement the following:a. Implement a print function with array and size parameters. This function should print the array using pointer arithmetic.b. Overload the print function to accept array, size and index parameters. If the index is between 1 and size-2 inclusive: Use pointer arithmetic to print: 1. the value at index 2. the value previous to the index 3. the value after the index c. Implement a sum function with array and size parameters. This function should return sum of the array, and use pointer arithmetic.d. Implement a average function with array and size parameters. This function shouldreturn average of the array, and use pointer arithmetic.e. Use provided main function to test your functions. ( Do not change the int main the question has provided. Included a snip of the int main function. Output has to be the same as shown in the snips)

Task 2: Login System Implement the function loginUser() that takes two String as input, one for user email and another for password. It will search for the given user email in emailArr. If the user email exists and the given password matches with the stored one against that email, then login will be successful and you should return the array index plus show a success message. Otherwise, login will be unsuccessful and you should return FAIL_VAL plus show a proper error message.

4. Insertion Sort• The idea with an insertion sort is that a sorted region grows one item at atime, by inserting an item into its correct position within the sorted region.• As done in Part 1, fill an array with random numbers.• Write a function that inserts an item into a sorted region of an array. Passthe function the index of the item to be inserted (i.e. the index of the firstitem in the unsorted region). Insert that item by shifting items over oneposition, until you have found the correct location to insert the item.• E.g. if given a = [2 5 8 9 6 3 7] and the index 4, a[4] should be inserted into thesorted portion, giving [2 5 6 8 9 3 7]• Write a second function that calls the first function repeatedly, until theentire array is sorted. (Each time the first function is called, it will insert anitem into a larger sorted region.)

19-8) isMember Function Write a recursive Boolean function named isMember. The function should accept three arguments: an int array, an int index number holding the size of the array and an int value to be searched for. The function should return true if the value is found in the array, or false if the value is not found in the array. Demonstrate the function in a driver program. --ORIGINAL QUESTION (Had no index variable and no type on the array)- 19-6) Recursive Power Function Write a function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a nonnegative integer. Demonstrate the function in a program.

Part 2: Advanced Queue (optional) Exercise 1. Priority Queue Based on the above program, create a function void priorityQueue (queue q), which accept current queue and insert new priority queue (int) at the front of the current queue Thus all items in current queue after inserting the new priority item will be moved. Simulate the priority queue by using random Boolean event. Pseudo Code: function priorityQueue (queue q) boolean priority = random Boolean //random Boolean event queue tmp if priority then get front q pop front to tmp while q is not empty get front from q new = front+1 pop from q push new to tmp end while else return q return tmp end function
12) Fun With Mergesort. Given the recursive mergesort function below. Modify the msort function such that, msort calls msort for sub arrays with more than 1024 elements, and msort calls bsort for sub arrays with 1024 or less elements. Assume both functions operate on the same global array. int data[4294967296]; // REALLY BIG array void bsort (int f, int 1); // forward declaration void msort (int f, int 1) int m; if (f<1) { m - (f+1)/2; msort (f, m): msort (m+1,1): merge (f,m, 1);
