Modified Code

this is the correct code
i have also update the above link as well

steps followed are simple same as floyd’s algorithms

  1. take two pointers fast and slow move both accordingly

  2. if they meet cycle present otherwise not

  3. now point slow to head and fast to one step ahead
    and move both single step
    where fast->next==slow->next cycle is present at that point

so just do fast->next=NULL;
