**Task:“Compute the sum of all the values in the nodes of a single linked list”**

The only thing is needed to solve this problem is linked list traversal. So we can easily modify function getLenght into following solution:

```
```

public int getSum(Node head)

{

if (head == null)

return 0;

else return getSum(head.next) + head.value;

}

Think how would you modify this function to implement search for the value in linked list.
