17,352 Points@11:50 DRY principle in replacing merged head to next node head ?
@ 11:50 Pasan writes the following code:
# Discard fake head and set first merged node as head
head = merged.head.next_node
merged.head = head
But can't it be simplified to the following?
# Discard fake head and set first merged node as head
merged.head = merged.head.next_node

Either way, the "DRY" principle doesn't apply here, since nothing is being repeated.
