sorting - 在Dart中手动排序

void main() {
  List data = [5,4,2,7,8,3];
  List sortedData = [];


    while (data.isNotEmpty)
    {
        // pop out the first element
       int tmp = data.removeLast();

        // while temporary stack is not empty and top
        // of stack is greater than temp
        while (sortedData.isNotEmpty && sortedData[sortedData.length - 1] > tmp)
        {
            // pop from temporary stack and push
            // it to the input stack
            data.addAll(sortedData.removeLast());
        }

        // push temp in tempory of stack
        sortedData.add(tmp);
    }

  print(data);
  print(sortedData);
}

未捕获的错误:TypeError:8:类型'JSInt'不是'Iterable'类型的子类型

我在这里做错了什么？

最佳答案

data.addAll(sortedData.removeLast());应该是data.add(sortedData.removeLast());
