hello @manikjindal49

pls explain what u r trying here->

        Node *next=slow->next,*curr=slow->next;
        Node *check=slow,*check2=slow->next;
        Node *prev=slow;
        while(curr!=NULL){
            next=curr->next;
            curr->next=prev;
            prev=curr;
            curr=next;
        }

Actually i am trying to reverse the second half of list and where i am using check is that so that the traversal canstop in next while loop

#4

check now->

#5

I understand all the things but I have one doubt AS why we are taking fast =head->next because if we want to find out the middle of the linked list we have to use fast =head not fast=head->next

#6

@manikjindal49

both will give middle only.

in case of even length there are two middles. we want slow to stop on left middle thats why started head from head->next
