O(n)用字符串比較兩個數(shù)字。（1）長度長的數(shù)字一定大。（2）如果長度相同，直接兩個字符串比較。var i,j,n:longint; s,a:string;begin readln(n); readln(a); j:=1; for i:=2 to n do begin readln(s); if length(s)>length(a) then begin a:=s;j:=i;end else if length(s)=length(a) then if s>a then begin a:=s;j:=i;end; end; writeln(j); writeln(a);end.
