Hi vipin

  1. In reverse func, while loop to reverse use condition while(count-- && curr!=NULL)
  2. In kreverse func , in while loop use condition while(head!=NULL)
    It will get right answers. But
  3. You are breaking the list in parts of k units each and not keeping track of parts. You need the build single combined list with every k units reversed.

Hope it helps
Mark resolved if satisfied :slight_smile:

@shivansh1498 thanks my code is working fine but Is this approach which i was using was totally wrong and if it does i am not getting how to reverse k elements in a list without breaking.

The approach you are using to reverse k elements of a list is perfectly fine but you need the combine a single list. Refer to this for the correct approach :
