背景
一位打字员回到家后，发现一些重要的信件仍需加重。为了确保他审核文本正确，他将文本字符bh vjaracter t0确定为6he。但是，他仍然设法错过了一些钥匙。
您的任务是编写模仿其ttping的cose。为了最大程度地减少错误的发生，代码应尽可能短。
键盘
键盘是标准的ANSI键盘。在下图中，红色文本显示了键的宽度。所有行均为1单位高，未标记的键为1单位宽。
这些键执行以下操作（列出只是为了防止混淆）：
- Shift本身不会执行任何操作，但是如果在常规键之前立即按Shift键，则会更改结果。
- CapsLock切换Caps Lock。如果启用了Caps Lock，则字母键将输出反大小写的字母。
- Backspace删除最后输出的字符（如果有）。
- Tab，Return和Space分别插入一个制表符，换行符和空格。
- Ctrl，Alt只是用于演示。他们（并完全缺少键盘）什么也不做。
- 所有字母键都会产生标记的小写字母。如果在它们之前按Shift键，则会产生大写字母。Caps Lock可逆转情况。
- 所有其他键产生中间标记的字符。如果在他们之前按Shift键，则会产生在顶部标记的字符。
打字
为了生成一个字符，打字员在键盘上找到它并检查是否需要按Shift键。如果是这样，他首先尝试按住Shift键。然后，他立即尝试按目标键并释放所有Shift键。在尝试按目标键之后，他必须严格释放Shift键。
然而，由于醉酒，他经常错过钥匙。这可以通过以下方法模拟：选择一个随机角度（均匀地），在该方向上将按压位置移动一个随机量（具有适当的分布），然后按下落下的按键。
挑战
作为输入，您将收到要写入的文本和指示醉酒程度的数字参数。您将输出醉酒打字员键入的文本，以及上述算法生成的错别字。
技术指标
- 输入文本将仅包含可打印的ASCII，制表符和换行符。
- 输入参数是某种标量数值。可以在答案中指定其范围，但增大该值应增加平均未命中距离，反之亦然。
- 您可以将键盘缩放到任何内部尺寸；上面的单位大小仅是示例。
- 使用的坐标必须精确到关键高度的千分之一。
- 该程序应为每次调用产生不同的结果。（诸如
srand(time(NULL));每秒更改之类的东西就足够了。） - 遗漏距离的分布可以是正态分布，也可以是其他类似的分布（较小值的大概率，对于较大值则迅速减小；例如，负指数就可以了）。
- 打字员的手指只有一点。无需考虑其半径。
- 打字员可以瞄准钥匙内的任何地方，只要它不在边缘上即可。中心，恒定位置等有效。
- 选择Shift键的方式可以是任何方式。允许进行恒定选择，但是如果错过Shift键的地方到此结束，则两个Shift键都需要起作用。
- 如果按住Shift键，则仅会影响该键（即在另一个键之前尝试Shift键并成功按下）。按下Shift键的“普通”键不起作用。
- Shift键仅在真实键之前被按下并快速释放，因此如果按住错误的键，则不会重复字符。
示例I / O
以下所有示例均来自参考解决方案，该解决方案使用距离的正态分布并始终选择左Shift。选项卡以SE表示为空格，但应显示在实际输出中。

Code golf is a type of recreational computer programming competition in which participants strive to achieve the shortest possible source code that implements a certain algorithm. Code golf should not be confused with sizecoding, a contest to achieve the smallest binary executable code. Playing code golf is known as "golf scripting". Code golf tournaments may also be named with the programming language used (for example Perl golf).
