Another possibility, which we observed in your print function is:

temp = tail -> next ;
do {
count++;
temp = temp -> next;
}
while ( temp!=tail->next);

This forces the function to atleast carry out the loop once (the first time when temp = tail -> next ) and it stops the next time temp = tail -> next.

Too much exited for upcoming videos these are really helpful

[AdityaMukherjee-ojlf]

Sir, can we initialize the count variable with 1?

[AbdurRahman-phms]

thank you for making this presentation😍

[vishalgiri]

sir please increase speed of uploading videos atleast 2 in one day in data structure playlist

[Rpshailu]

if int count is initialized by 1 then we don't need count++ after while loop?

[DaiMoscv]

Here is another variation:

int countList(struct node* tail) {
if(tail == NULL)
return 0;
if(tail->next == tail)
return 1;
struct node *temp = tail->next;
int count = 1;
while(temp != tail) {
count++;
temp = temp->next;
}
return count;
}

Is there any way to count the nodes using only one pointer ie reference to a node (without declaring the temp pointer)??

[gowriv]

Sir what about control system and aptitude please upload the vedios.

[preranakokane]

Waiting for videos on stack data structure

[iamsrinandavikassadhanala]

Sir when will the complete Data Structures be uploaded ?

[nikhilsastry]

We want C++ course from you guys..please🥺

[mohdsarim]

sir avl tree implementation krwa do please ..

[anjalisoni]

this is too good after code with harry ....the way presenting and explaining are too good
