题解 | 从单向链表中删除指定值的节点

from typing import Optional

class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next


data = input().split()
node_num,node_head,node,delete_node = data[0],data[1],data[2:-1],data[-1]

data_node = []
for i in range(0,len(node),2):
    data_node.append(tuple(node[i:i+2][::-1]))
result = []
for i in data_node:
    node_list = ListNode(i[0],ListNode(i[1]))
    if len(result) == 0:
        result.append(node_list.val)
        result.append(node_list.next.val)
    elif int(node_list.val) == int(result[-1]):
        result.append(node_list.next.val)
    
    elif int(node_list.val) != int(result[-1]):
        result.insert(result.index(node_list.val)+1,node_list.next.val)

result.remove(delete_node)
print(' '.join(result))

做的稀里糊涂的，莫名其妙就出来了，可能只适用于这个题吧
