Line 34 changes block_index to 1; on the second iteration of the while loop, the check on lines 21 22 is also false because array_in_use[1] is -1. The code to advance block_index on line 34, instead of changing it to 2 as it should, instead moves it back to 0.

In both cases, the code immediately returns new_element as the new head of the list. For example, in the first hint, the existing list is non-empty, but the new entry becomes the new head of the list, so the list is modified on line 21 and the new head is returned on line 22.
