Damn, I spent like 40 min trying to solve this problem and when I looked at your solution, I realised that this problem is way simpler than I expected.

I think node name before _head is little confusing .It is actually storing head of list of node elements smaller than x if I am not wrong .It could be renamed as before _x because that's the point where final list would look partitioned. Moreover head is moving and elements pointed by head is continuously changing.

How come 4 comes before 3 in the output ?

[madetolaugh]

What is the meaning of this line - ListNode before_head = new ListNode(0); ? I am confused why he wrote 0 at the last

I feel wayy better when I return after_head;
