自己写的一个delphi正整数快速排序

type
  TIntArr= array of word;

procedure MyQSort(var arr: TIntArr; low: word; high: word); //word可以改为自己需要的类型
var
   i, j , x, k : word;
begin
   if low < high then
   begin
      i:= low;
      j:= high + 1;
      while True do
      begin
        repeat
          Inc(i);
        until  ((arr[low] <= arr[i])or(i = high));
        repeat
          Dec(j);
        until  ((arr[low] >= arr[j])or(j = low));
        if i<j then
        begin
          x:= arr[j];
          arr[j]:= arr[i];
          arr[i]:= x;
        end
        else
          Break;

      end;

      x:= arr[j];
      arr[j]:= arr[low];
      arr[low]:=x;

      if(j>1)then
        MyQSort(arr, low, j-1);
      if(high-j-1 > 1) then
        MyQSort(arr, j+1, high);

   end;

end;
