linked list fill the gaps question..

i have a struct

Code:

typedef struct item{
int number;  //the number  
int occur;    // the number of ocuurances of this number
	struct item *next;
}item;

i need to compete the gaps of the following structure
so it will reduse the duplicates of a certain item in the original list
and puts the total number of the occurances of a item into its item.number struct.
for example

Code:

void reduce(item *head){
	item* temp;
	int count =  ?? 1 ??;

	if ??  2  ?? ;

	while(??  3  ??)
		if( ?? 4 ?? ){
			??  5  ??;
			  ?? 6 ??;
			??   7 ?? ;
			count++;
		}
		else{
			head->occur = count;
			?? 8 ?? ;
			?? 9 ?? ;
		}
	?? 10 ?? ;
	
}

i tried to fill some but i can see what each block of the given structure should do in general

Code:

void reduce(item *head){
	item* temp;
	int count =  0;

	if (!head) return;

	while(temp)
		if(head->number==head->next->number ){
			temp=head->next;
			  head->next=head->next->next;
			free(temp) ;
			count++;
		}
		else{
			head->occur = count;
			head=head->next;
			?? 9 ?? ;
		}
	?? 10 ?? ;
	
}

Should you be closing it in a while block?

No, he should stop posting his homework without even trying anything!
