(Codewars) Linked Lists-Sorted Insert

Kata: https://www.codewars.com/kata/linked-lists-sorted-insert



Description




Write a SortedInsert() function which inserts a node into the correct location of a pre-sorted linked list which is sorted in ascending order. SortedInsert takes the head of a linked list and data used to create a node as arguments. SortedInsert() should also return the head of the list.



sortedInsert(1 -> 2 -> 3 -> null, 4) === 1 -> 2 -> 3 -> 4 -> null)
sortedInsert(1 -> 7 -> 8 -> null, 5) === 1 -> 5 -> 7 -> 8 -> null)
sortedInsert(3 -> 5 -> 9 -> null, 7) === 3 -> 5 -> 7 -> 9 -> null)





My Solution



def sorted_insert(head, data):
prev = None
node_j = head
node_i = Node(data)
while node_j:
if node_j.data > data:
node_i.next = node_j
break
prev = node_j
node_j = node_j.next
else:
node_i.next = None
if prev:
prev.next = node_i
return head if prev else node_i
