请考虑以下任务：

给定正整数n> 0，输出其整数平方根。整数平方根若干Ñ是最大的值X，其中X ² ≤Ñ，通常用下式表示floor(sqrt(n))。

例如：25 -> 5，24 -> 4，40 -> 6，1 -> 1。

该任务本身很容易完成。但是，在这个挑战中，您的任务是仅使用25个字符来解决尽可能多的语言问题。

例

首先，您需要选择一组 25个字节（无重复）。它可能看起来像这样（注意前导空格）：

 ()*-.05:=>Mabdhilmnqrst|

然后，您面临的挑战是仅使用此集合中的字符，以尽可能多的基于文本的语言（对不起，Piet）来构造问题的解决方案。您可以根据需要多次使用字符，但是一定不能在集合之外使用字符。

解决方案可以是完整的程序或功能，但不能是代码段。例如，使用这组字符，我可以这样做：

M -> (int) Math.sqrt(M)    // Java (lambda expression)
M => Math.sqrt(M)|0        // Javascript (unnamed function)
lambda M: int(M**.5)       // Python (lambda function)

由于我使用了3种语言，因此我得到3分。

请在答案中还包括您正在使用的字节组。

规则

• 这是一个罗塞塔石的挑战-你的分数是语言您提交包括数量。最高分获胜。有标准漏洞。
• 对于此挑战，“语言”被视为一种截然不同的编程语言-禁止使用同一语言的多个版本（Python 2，Python 3等）。
• 程序仅需要为语言的标准整数范围内的输入工作。
• 不允许使用源代码完全相同的程序（polyglots）。
• 更具体地说，它是一组字节，而不是字符-因此您可以将05AB1E £和Jelly ɱ用作相同的字符（因为它们具有相同的代码点）。

请不要觉得您必须击败所有其他解决方案-如果您有有趣的答案，请发布！

(q((input)(sqrt 1 1 input)))

sqrt是一个辅助函数，其参数为：当前的guess n，n平方和input数字。如果input小于nsqr，则说明我们走得太远，因此返回n负1；否则，返回负1。否则，递归，加入1〜n并加入n + n + 1到nsqr。（数学运算有点复杂，因为tinylisp仅内置了减法。）第二行定义了我们的实际函数，该函数采用一个整数并从1开始input返回结果。sqrtn
