在[46.全排列](https://programmercarl.com/0046.全排列.html)中已经详细讲解了排列问题的写法，在[40.组合总和II](https://programmercarl.com/0040.组合总和II.html) 、[90.子集II](https://programmercarl.com/0090.子集II.html)中详细讲解了去重的写法，所以这次我就不用回溯三部曲分析了，直接给出代码，如下： 在[46.全排列](https://programmercarl.com/0046.全排列.html)中已经详细讲解了排列问题的写法，在[40.组合总和II](https://programmercarl.com/0040.组合总和II.html) 、[90.子集II](https://programmercarl.com/0090.子集II.html)中详细讲解了去重的写法，所以这次我就不用回溯三部曲分析了，直接给出代码，如下：
