Test #1: 8 4 10 10 8 10 4 7 15 5 8 6 5 8 6 13 9 11 2 9 1 18 16 15 14 16 15 13 18 15 17 18 6 1
输出应该是 not exit。但,却提示“wrong answer 1st words differ - expected: '7', found: 'not'”
Test #2: 9 7 7 20 17 6 4 7 4 20 19 4 17 15 7 15 5 16 10 3 5 13 5 19 16 14 5 9 3 10 2 16 12 4 17 6 5 18 16 5 9... 该用例无法完整展示,但,大概率,这个答案也是错误的。
By the way,不存在时的输出的英文错了。得是 not exist,不能是 not exit
