Sir please videos of coding interview questions on data structures topic wise
Like first some coding questions on arrays then some questions on stacks and so on...

i am not understanding why pos variable is put in the while loop as pos>2; how do we assume that the position entered by the user in the main function not less than 2?

[rishavsaha]

imo this piece of code would work for any position 1st too.

// ---delete a node at a certain position---
struct node *delAnyPos(struct node *tail, int pos)
{
if (tail == NULL)
return NULL;
if (tail->next == tail)
{
free(tail);
tail = NULL;
return NULL;
}
struct node *temp1, *temp2;
temp1 = tail->next;
if (pos == 1)
{
tail->next = temp1->next;
free(temp1);
temp1 = NULL;
return tail;
}
pos--;
while (--pos)
temp1 = temp1->next;
temp2 = temp1->next;
temp1->next = temp2->next;
if (temp2 == tail)
tail = temp1;
free(temp2);
temp2 = NULL;
return tail;
}

What about the case when position of the node to be deleted is 1 .I think the code would change for that case too.

[sahilgoswami]

The same program is not showing the output
It is getting exited after the 2nd value of the linked list is given

[Adityasharma-oezp]

Did anyone noticed that tail has address 3000 and and position has 4000
And now temp2 and tail both has address 4000😂
