cp -n /web/cs1511/19T2/activities/list_sum/list_sum.c .Your task is to add code to this function in list_sum.c:
// Return the sum of the elements in the linked list pointed by head
int sum(struct node *head) {
// PUT YOUR CODE HERE (change the next line!)
return 42;
}
sum is given one argument, head, which is the pointer to
the first node in a linked list.
Add code to sum so that its returns the sum of the list.
For example if the linked list contains these 8 elements:
1, 7, 8, 9, 13, 19, 21, 42
sum should return 120 because
1 + 7 + 8 + 9 + 13 + 19 + 21 + 42 = 120.

Do not change this main function. If you want to change it, you have misread the question.
Your list_sum function will be called directly in marking. The main function is only to let you test your list_sum function
Here is how you use main function allows you to test list_sum:
dcc list_sum.c -o list_sum ./list_sum 1 2 4 8 16 32 64 128 256 511 ./list_sum 2 4 6 5 8 9 34 ./list_sum 13 15 17 17 18 80 ./list_sum 42 4 46 ./list_sum 0
sum should not change the linked list it is given. Your function should not change the next or data fields of list nodes.
sum should not use arrays.
sum should not call malloc.
sum should not call scanf (or getchar or fgets).
sum should not print anything. It should not call printf.
Do not change the supplied main function. It will not be tested or marked.
When you think your program is working you can use
autotest to run some simple automated tests:

cp -n /web/cs1511/19T2/activities/list_count_favourite/list_count_favourite.c .Your task is to add code to this function in list_count_favourite.c:
// Return the number of elements divisible by 17 in the linked list
int count_favourite(struct node *head) {
// PUT YOUR CODE HERE (change the next line!)
return 42;
}
count_favourite is given one argument, head, which is
the pointer to the first node in a linked list.
Add code to count_favourite so that its returns the number of elements divisible by 17 in the list.
For example if the linked list contains these 8 elements:
51, 7, 8, 9, 34, 19, 34, 42
count_favourite should return 3 because 51, 34 and 34 are divisible by 17.

cp -n /web/cs1511/19T2/activities/list_get_nth/list_get_nth.c .Your task is to add code to this function in list_get_nth.c:
// Return the n-th element of linked list.
// n == 0 returns first element, n == 1, second element, ....
int get_nth(int n, struct node *head) {
// PUT YOUR CODE HERE (change the next line!)
return 42;
}
get_nth is given two arguments, an int n and
head, which is the pointer to the first node in a linked list.
Add code to get_nth so that its returns the n-th element the linked element of the linked list.
The elements are counted in the same manner as array elements (zero-based), so the first element in the list is regarded as at position 0, the second element position 1 and so on.
get_nth can assume that the list contains at least
n + 1 elements.
For example if the linked list contains these 8 elements:
1, 7, 8, 9, 13, 19, 21, 42
if n is 1 get_nth should return 7.
