1) k번째 접근 함수 만들기
2) n-k 번째 접근
class Node:
def __init__(self, data):
self.data = data

class LinkedList:

self.head = Node(value)
def append(self, value):

while cur.next is not None:
cur = cur.next
cur.next = Node(value)
def get_kth_node_from_last(self, k):
# 구현해보세요!
#뒤에서 k 번째 -> 앞에서 n-k+1번째
#5에서 2번째 -> 앞에서 (5-2)+1=4번째
cur = self.head
length =0
while cur is not None:
length += 1
cur = cur.next
print("length",length)
end_length = length - k
cur = self.head
for n in range(end_length): # end_length 번째
cur = cur.next
return cur
linked_list = LinkedList(6)
linked_list.append(7)
linked_list.append(8)
print(linked_list.get_kth_node_from_last(2).data) # 7이 나와야 합니다!
#print(linked_list.get_kth_node_from_first(3).data)
