What is the primary function of heat shock proteins in cellular stress response?

a) Given the head of a singly linked list, write a function that returns the product of the second half of the linked list. [20 pts]}Assume the length of the linked list is divisible by 2.[15 pts] Example: For the linked list: 2 → 3 → 4 → 5 → 6 → 7Your function should return 210 (5 * 6 * 7). #include struct ListNode {    int val;    ListNode* next;    ListNode(int x) : val(x), next(nullptr) {}}; int productSecondHalf(ListNode* head) {    //to do…} You may not use a loop to determine the size of the linked list. Use fast and slow pointers instead. b)What is the time complexity of this approach? Explain. [5 pts]
