Appending unique values only in a linked list in C
- by LuckySlevin
typedef struct child {int count; char word[100]; inner_list*next;} child;
typedef struct parent
{ char data [100];
inner_list * head;
int count;
outer_list * next; } parent;
void append(child **q,char num[100],int size)
{ child *temp,*r,*temp2,*temp3;
parent *out=NULL;
temp = *q;
temp2 = *q;
temp3 = *q;
char *str;
if(*q==NULL)
{ temp = (child *)malloc(sizeof(child));
strcpy(temp->word,num);
temp->count =size;
temp->next=NULL;
*q=temp;
}
else
{ temp = *q;
while(temp->next !=NULL)
{ temp=temp->next;
}
r = (child *)malloc(sizeof(child));
strcpy(r->word,num);
r->count = size;
r->next=NULL;
temp->next=r;
}
}
This is my append function which I use for adding an element to my child list. But my problem is it only should append unique values which are followed by a string. Which means :
Inputs : aaa bbb aaa ccc aaa bbb ccc aaa
Append should act :
For aaa string there should be a list like bbb->ccc(Not bbb->ccc->bbb since bbb is already there if bbb is coming more than one time it should be increase count only.)
For bbb string there should be list like aaa->ccc only
For ccc string there should be list like aaa only
I hope i could make myself clear. Is there any ideas? Please ask for further info.
