SQL函数 SIGN返回给定数值表达式符号的数值函数。 SIGN 返回 SMALLINT 数据类型。描述SIGN 返回以下内容: -1 如果 numeric-expression 小于零。 SIGN 可用作 ODBC 标量函数(使用花括号语法)或 SQL 通用函数。SIGN 在确定其值之前将数值表达式转换为规范形式。 例如,SIGN(-+-+3) 和 SIGN(-3+5) 都返回 1,表示一个正数。注意:两个负号(连字符)是内嵌注释指示符。因此,指定两个连续负号的 SIGN 参数必须显示为用引号括起来的数字字符串。 示例以下示例显示了 SIGN 的效果:SELECT SIGN(-49) AS PosNeg-1SELECT {fn SIGN(-0.0)} AS PosNeg0SELECT SIGN(-+-16.748

Largest Plus Sign Problem: In a 2D grid from (0, 0) to (N-1, N-1), every cell contains a 1, except What is the largest axis-aligned plus sign of 1s contained in the grid? Return the order of the plus sign. If there is none, return 0. An “axis-aligned plus sign of 1s of order k” has some center grid[x][y] = 1 along with 4 arms of length sign is checked for 1s.
淘宝sign加密算法 淘宝对于h5的访问采用了和客户端不同的方式,由于在h5的js代码中保存appsercret具有较高的风险,mtop采用了随机分配令牌的方式,为每个访问端分配一个token,保存在用户的 cookie中,通过cookie带回服务端分配的token, 客户端利用分配的token对请求的URL参数生成摘要值sign, MTOP利用这个摘用值和cookie中的token来防止URL篡改。 第二次请求时,js通过读取cookie中的token值,按照约定的算法生成sign, sign在mtop的请求中带上,mtop通过cookie中和token用同样的方式计算出sign,与请求的sign进行比较 生成 关于sign的生成公式: md5Hex(token&t&appKey&data) 如:md5Hex(“645d1f414d4914297dfaab40f3f76016 &1234&4272&{" itemNumId":"1500011132496"}”) sign=d2b2f818a03496b296b899a230c03abd token 关于cookie的有效时长,cookie的有效时长为
