def solution(cards):
result = 0
for card in cards:
result ^= card
return result

if __name__ == "__main__":
print(solution([1, 1, 2, 2, 3, 3, 4, 5, 5]) == 4)
print(solution([0, 1, 0, 1, 2]) == 2)
print(solution([7, 3, 3, 7, 10]) == 10)
================================
如题： result ^= card这个向上的箭头什么意思啊？
