Suppose we have a struct "node" defined as follows: struct node { int data; struct node * next; }; We also have a function named createNode that allocates a new node and sets its data field to the specified value. (The next field is set to NULL.) struct node * createNode(int val); Variable n1 points to a struct node that has already been created and initialized. Variable n2 is a struct node pointer, and its current value is NULL. Write a statement, or sequence of statements, that creates a new node, sets its data equal to 1 more than n1's data, and makes n1's next field point to the new node. (In the previous sentence, we've used "n1" to mean "the struct that n1 points to".) Do not change the value of n1.
