自己编写小程序背日语50音图

这是个啥

简而言之呢就是最近心血来潮打算自学日语，学日语自然就要先从50音图开始，就是下面这个：

可以看出来50音图横向是按照a i u e o这5个元音顺序，纵向按照a ka sa ta na ha ma ya ra wa 的顺序排布的。按顺序编排自然是为了方便记忆，但是也容易按照顺序能背出来，打乱顺序是否还能快速正确的念出来呢？那我可不可以写个小程序，随机给我出题，让我作答呢？
就类似这样：

mo的写法是：
も
すごい，正しい答！！！
く的读音是：
ku
すごい，正しい答！！！

所以就很简单写了一个小程序。由于我有点强迫症，像ya，ma两行不是完整的5个，所以我还是使用空格填充了，让两个数组看起来整齐一点，所以代码里有対空格的判断跳过。还有有些读音应该是si、ti，我写成了shi和chi，这个看大家自己喜欢吧，可以改。

目前支持以下几项功能：
1.支持输入出多少道题
2.可以根据字形，输入读音；也可以根据读音，输入字形
3.题是随机出的
4.回答错误会给出正确答案

后续大家有兴趣的可以迭代以下几个小功能：
1.目前随机是random函数直接随机的，没有加权重判断，可以增加按照已经出过的题答对答错的次数来增加权重因子，完成错题集的能力
2.日语键盘和英文键盘切换有点麻烦，目前出字形题和字音题是随机的，可以考虑先字形再字音，减少键盘切换的频率
