    Jest encountered an unexpected token

    Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.

    Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.

cpp 版显示 wrong answer，没有输出, python 版显示 runtime error，没有提示，但是本地测试过测试用例都没有问题，算法应该是正确的。
