```java
public class IntNode
{
public int info;
public IntNode next;
}
```

a) Write code to add 50 to the appropriate field of the node pointed to by temp.

```java
temp.info += 50;
```

b) Write code to remove from the list the item after temp.
```java
temp.next = temp.next.next;
```

c) Write the code to remove from the list temp.
```java
temp.info = temp.next.info; // Assign the next node's value to temp - this will overwrite temp's value.
temp.next = temp.next.next; // Set the pointer for temp's next node to the node after the value taken for temp - this effectively clones temp.next and replaces temp.
```

d) Write code to go through the list and to sum all the values within the list. You may assume the existence of head, a reference to the start of the list.

```java
IntNode current = head;
int sum = 0;
while ( current != null ) {
	sum += current.info;
	current = current.next;
}
```
