typedef struct node_t node_t; struct node_t { }; int32_t value; node_t* next; node_t* insert (node_t* list, int32_t v, int32_t* flag); 3) As you may have noticed from MT1, Howie is lazy. He wants you to write the interface for the following implementation of function copy_to_linked_list. He really appreciates your help! /* copy_to_linked_list int32_t copy_to_linked_list (int32_t a[], int32_t size, node_t** list_p) { int32_t flag, i; for (i = 0; i < size; ++i) { *list_p = insert (*list_p, a[i], &flag); if (-1== flag) return -1; } return 0;
For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }

in c++ Write a function that takes a queue with 20 integer values and deletes the elements thatare between 15 and 20. In other words, only the elements less than 15 or greater than 20remain in the queue. This means that you need to have an auxiliary queue to store theelements between 15 and 20 and restore them back to the original queue.

card_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.
You have a sorted linked list. Fill in the missing code in the following function. SortedType::DeleteItem(Item Type item) // pointer delete //trailing pointer // traveling pointer void { NodePtr tempPtr; NodePtr predLoc; NodePtr location: bool found false; // Find item to delete: Put your code below //delete item: Put your code below
