取平均数递归法，最多计算6次就可得出结果
欢迎测试～（存Bat）

Loop
Sub Bisection(low,high,s)

if s<=7 then
Select Case Cstr(Math(Mid_))
Case "="
wscript.echo "Win!The number is "&Mid_
Case ">"

Bisection Low,Mid_,s+1

不过偶尔还会出现下标越界。而且有几次计算了20多次才猜中正确的数，你的算法还不是标准二分，比较费内存。如果是猜测1到10000之内的数，你的程序就非常缓慢。把那个递归取消了，有递归的都不是标准二分。

嗯，猜20多次是因为服务端数字变更了(正常最多7次)
下标越界是服务器没返回JSON，导致无法分割得到符号
尴尬的是，0和100不在范围里面(失误，已修正)……
总之就是递归然后除2取整
当时一脑抽就用的递归而不是循环╮(╯_╰)╭
算是自己研发的变种了吧
感谢大佬鼓励<v<

以下是模仿了happy和ro的程序写的。经过几次修改，应该是能比较长时间持续运行了。
这个网站一言不合就返回500错误或者无规律清空数据，在刚开始很困扰，很懵B。

后来长时间运行发现，也有可能极小概率请求后返回404或者跳转到首页。所以也必须要在关键代码上处理错误。
→_→代码丑。但是管用。

把细节都考虑进去了，如果把user-agent修改为火狐浏览器，就好了。这个php服务器对py的请求会拒绝，只能伪造user-agent来实现高速和稳定的请求。

my $test = int(($max + $min) / 2);

无规律清空是因为我偷懒没用数据库导致多人请求时同时写文件挂掉
