- Answer each question given this definition of a linked list. struct ListNode { // a data type double value; ListNode *next; }; ListNode *head; Write C++ statements to output the sum of the numbers in the list. Write C++ statements to output the value of the second-to-last node (the one preceding the last node). You may assume the list contains at least two nodes (maybe more). Given the following list, write C++ statements to remove the node containing 3.2 (and deallocate it). Assume p is of type ListNode * and is already pointing to 1.2. You may declare and use another pointer, but do not use a loop, do not change p, do not use head. head -> 1.2 -> 3.2 -> 7.7 -> null The template code below has already constructed this list. #include <iostream>using namespace std; struct ListNode // the node data type{double value; // dataListNode *next; // ptr to next node}; int main() {//set up a list with 3 elements (done):ListNode *head = NULL;ListNode *newNode = new…Hi, can you do it in PYTHON def delete_item(...): """ param: info_list - a list from which to remove an item param: idx (str) - a string that is expected to contain an integer index of an item in the in_list param: start_idx (int) - an expected starting value for idx (default is 0); gets subtracted from idx for 0-based indexing The function first checks if info_list is empty.
