此字符串分割函数用delphi编写,可以适应字符串中存在双字节字符和单字节字符. function TricheditEfm.SplitString(source:string;Sleng:Integer):TStringlist;stdcall; //字符串分割函数 ,按字符串长度分割 var copycount,i:Integer; //每个汉字占用两个字节长度 copystr:string; stringlist:Tstringlist; begin Stringlist:=Tstring
Given a non-empty string, encode the string such that its encoded length is the shortest. The encoding rule is: k[encoded_string], where the encoded_string inside the square brackets is being repeated exactly k times. Note: k will be a positive integ
