请问楼主，你面试的职位是正式员工还是第三方呢？和我联系的猎头说那边正式员工的 hc 很少。

个人看法，首先要分清把梦想和欲望分清楚；此外，痛苦多是来源“横向比较”，人要多“纵向比较”；最后，俯仰一生，譬如朝露，找到乐子做，让自己快乐起来吧

```java
public class EatBreadQuestion {

private static final String STR_1 = "1 ";
private static final String STR_2 = "2 ";

public static void printAllCombination(int breadSize) {
print("", breadSize);
}

private static void print(String beforeInfo, int breadSize) {
if (breadSize > 1) {
print(beforeInfo + STR_1, breadSize - 1);
print(beforeInfo + STR_2, breadSize - 2);
} else if (breadSize == 1) {
print(beforeInfo + STR_1, breadSize - 1);
} else {
System.out.println(beforeInfo);
}
}

public static void main(String[] args) {
printAllCombination(1);
}

}
```

@auroraccc 可以说几个名字吗？感谢

```
Map<Integer, List<User>> parentIdUserMap = userResource.stream()
.filter(u -> u.getParentId() != null)
.collect(groupingBy(User::getParentId));

userResource.stream().filter(u -> u.getParentId() == null).map(u -> {
u.setUserList(parentIdUserMap.get(u.getId()));
return u;
}).collect(toList());
```

好奇哪里可以买卖脚本
