这么写cmp：
```cpp
bool cmp(string x,string y)
{
return x+y>y+x;//y放x后和x放y后
}
你这么写这组数据不过2 87 876

```cpp
var n,i,j:longint;
sum:string;
s:array[1..20] of string;
begin
readln(n);
for i:=1 to n do begin read(j);str(j,s[i]);end;
for i:=1 to n-1 do
for j:=i+1 to n do
if s[i]<s[j] then
begin
sum:=s[i];s[i]:=s[j];s[j]:=sum;
end;
for i:=1 to n do write(s[i]);writeln;
end.
