One thing is u can take a Struct Node *p pointer and make it equal to head of the node and apply while loop p!= NULL and make a vector and store all the values of the linked list. After that take the p pointer and make it equal to head again and do the process again now for every node just update the value of p->data = p->data + v[lenght-(i-1)] and increment i.
