If you dry run your code once tail1 is NULL initially and you are trying to access tail1->next which is resulting in a runtime error. Try to modify your code once within the given logic so that the code does not access tail->next when tail itself is NULL . (use if condition when tail1 is NULL) .i cant understand what you are saying if possible made change in the line which is giving run time error ,multiple time i have send my code but still unable to resolve my doubt pls resolve as soon as possible
Kreverse in linked list
@shrutikatyal hey do k=k%length of linked list ,then apply same logic as you have applied you will get it.
where i should apply k=k%length means in which line
@shrutikatyal hey you have to that in starting after taking the iput of k as this will handle the case when k>length of ll , please take a example and dry run it using that logic. Happy coding.
