【使用前先看介绍/有问题可反馈】UOOC 答案测试器 (UOOC Answer Tester):此脚本是通过试错得到 UOOC 测试题的单选题答案,请按照指示进行操作,请注意,此脚本并不能直接得到单选题的正确答案。此方法可行的原因是,小测成功提交的正确率需要在 70% 以上,利用这一点,在单选题较多时可以较大概率保证在试错的时候不会误提交。也就是说,在单选题题量很少的时候,并不适合使用该方法进行试错找答案。

                复制下述代码并回车执行
                AnswerTester.setOption('A');

                请手动提交该答卷,提交成功后复制下述代码并回车执行
                let r1 = AnswerTester.getOption();
                AnswerTester.setOption('B');

                请再次手动提交该答卷,提交成功后复制下述代码并回车执行
                let r2 = AnswerTester.getOption();
                AnswerTester.setOption('C');

                此时单选题的正确答案已经通过试错得到😄
