<h2><a href="https://leetcode.com/problems/remove-zero-sum-consecutive-nodes-from-linked-list/">1171. Remove Zero Sum Consecutive Nodes from Linked List</a></h2><h3>Medium</h3><hr><div><p>Given the <code>head</code> of a linked list, we repeatedly delete consecutive sequences of nodes that sum to <code>0</code> until there are no such sequences.</p>
2+
3+
<p>After doing so, return the head of the final linked list.&nbsp; You may return any such answer.</p>
4+
5+
<p>&nbsp;</p>
6+
<p>(Note that in the examples below, all sequences are serializations of <code>ListNode</code> objects.)</p>
