Sometimes you need to do different things based on different browsers.This requires us to check the browser and version.Qwrap BrowserCodeAs follows. VaR QW = {}; /* ** @ Class browser JS running environment, browser and version information. (Browser only performs sniffing Based on useragent, which is not rigorous .)* @ Singleton* @ Namespace QW */ QW. Browser = Function (){ VaR Na = Window. Navigator,UA =

data of a list is filtered, and all digital numeric data are sorted from small to large.> x=list(a=12,b=1:4,c=c(‘b‘,‘a‘))> y=pi> z=data.frame(a=rnorm(10),b=1:10)> a From the results found that only $z$a data are sorted, check the type of $z$b, found to be integer, is not equal to numeric, so there is no sorting.Next, the data of the string type is manipulated, all string literals are added as a string ' ++++ ', and non-string type data is set to NA.>

Ax offset address into the stack to Oeh; (2) JMP WORD PTR SS (because DS equals ss): [0EH], at which point the program jumps to Cs:ss:[oeh], because the value of Ss:[0eh] is 0, so jump to cs:0 to start execution,That is, the first statement of the program MOV AX; (3) when the program executes again to call word ptr ds:[0eh], the pointer jumps to Ds:[0eh], and at this point: [0eh] The value is not 0, it has become the last time the call was pressed on the stack of the INC The move address at AX,
