Getting an error in the output

#1


This is my code

#2

there are a lot of cases that u need to handle in this particular question
algo:

  1. make a even_head , odd_head pointing to LL with even and odd element respectively
  2. even_tail , odd_tail which are tail pointer to even and odd linked list
  3. for the first element of even and odd update the respective heads, make the tail point to the head
  4. when iteration is over
    a. even_tail->next = NULL ( else will go in infinite loop)
    b. check if odd head is NULL : means no odd elements simply return even_head
    c. if even_head == NULL then odd_tail->next = NULL
    else odd_tail->next = even_head
    return odd_head;
