Write a C function delete_last_occurwith thefollowing header:

void delete_last_occur (PTR *h, int j)

The parameter *h points to a listcontaining nodes of type NODE. When the list isnonempty, several

nodes in the list may have the same value forthe key field. The function should do the following.If

the list contains one or more nodes whose key values areequal to that of the parameter j, thefunction

should delete last node with key valueequal to that of j. If the list does not containany node with

keyvalue equal to that of j, the function should returnwithout modifying the list.
