昨天在 leetcode 刷题的时候遇到的问题,本地测试&WEB 上手动填写用例答案正确,提交答案时同样的用例答案显示错误.

提交记录

提交记录 11 / 64 个通过测试用例 状态：解答错误 最后执行的输入：6 [[0,1],[2,3],[4,5]]

代码(Python3)

from typing import List class Solution: lines = [] class PointLine: def __init__(self, p1, p2): self.point1 = p1 self.point2 = p2 pass def countPairs(self, n: int, edges: List[List[int]]) -> int: count = 0 already = set() for x in edges: self.lines.append(self.PointLine(x[0], x[1])) for x in range(n): for y in range(n): if x == y or already >= {x.__str__() + "|" + y.__str__(), }: continue already.add(x.__str__() + "|" + y.__str__()) already.add(y.__str__() + "|" + x.__str__()) if not self.find_way(x, y): count += 1 return count def find_way(self, p1, p2) -> bool: for n in self.lines: if ((n.point1 == p1 and n.point2 == p2) or (n.point1 == p2 and n.point2 == p1)): return True return False print(Solution().countPairs(6, [[0, 1], [2, 3], [4, 5]])) 

知道写的不是很优雅，这两天才学的 可是这是啥情况...
