Answer 6 is correct and well thought but there is a tiny
mistake.
the while loop should check upto the last node which it
doesn't and hence prints the wrong value ie. value of the
node before the fifth node from the end.
while(p!=NULL) would give the correct node.
Also while returning the value, decrementing curr_ct by 5 is
not really necessary.
return a[curr_ct%5]; would give the same value in all cases.
