你这个水平不走开发可惜了啊，其实开发我都觉得可惜了，应该努力读个研，出来搞算法，真的

@unt 那可以做的，实时录屏软件可以拿到屏幕信息，走 OCR 就行

实时翻译是可以做到，但是要实时修改其他 App 的 UI 内容做不到

下一步就要教怎么赚钱了，付费买课

没问题的，耐心等等吧，估计大老板要等到被业务催等着要人进来干活才会想起来给你发 offer

没人比你更清楚你的实际情况，有百万的现金流，低消费，无家庭负担，短时间生活肯定不是问题，完全可以探索副业，探索新人生路，但看 op 描述，似乎副业还不能带来收入，并且对副业的未来发展也没有明确规划，只是透露出对现在职业生活的厌倦，若是这样，推荐还是先稳住现金流，等副业有一定进展，再走。

我最近也在思考这个问题，最大的困局在于不做程序员做什么，受限于信息输入，不清楚自己想要什么，但是不想要现在的生活确实很清楚的，如果钱够的话，我觉得可以停下来休整一下，过一下不一样的生活，说不定会有新的见解

想问下过来人，到底要不要生娃，感觉总是听到带娃产生的矛盾

跟你差不多，虽然我不懦弱，但是性格也很内向，跟周围人很难处人际关系

@ccpp132 的确可以。。。加了个 tmp 保存原 cur ，然后`tmp->left = nullptr; `破坏就能通过了
```
class Solution {
public:

TreeNode *preNode(TreeNode *root) {
if (root == nullptr) return nullptr;
if (root->left == nullptr) return nullptr;
TreeNode *cur = root->left;
while (cur->right != nullptr) {
if (cur->right == root) {
break;
}
cur = cur->right;
}
return cur;
}

vector<int> inorderTraversal(TreeNode* root) {
if (root == nullptr) return {};
TreeNode *cur = root;
std::vector<int>res;

while (cur != nullptr) {
if (cur->left != nullptr) {
TreeNode *pre = preNode(cur);
if (pre->right != nullptr) {
res.push_back(cur->val);
cur = cur->right;
} else {
pre->right = cur;
TreeNode *tmp = cur;
cur = cur->left;
tmp->left = nullptr;
}
} else {
res.push_back(cur->val);
cur = cur->right;
}
}

return res;
}

};
```

@ccpp132 猜测是这样的，不过这样不能解释为啥上面的人转 go 可以跑通。。。我刚测试了一下 swift ，也是可以通的，代码如下，并没有加 pre->right = nil 这样的恢复操作，估计 C++的运行方式应该是有些不同
class Solution {
func preNode(_ root: TreeNode?) -> TreeNode? {
guard let root = root else {return nil}
if root.left == nil {return nil}
var cur = root.left
while cur?.right != nil {
if cur?.right === root {break}
cur = cur?.right
}
return cur
}

func inorderTraversal(_ root: TreeNode?) -> [Int] {
guard let root = root else {return []}
var cur: TreeNode? = root
var res: [Int] = []
while (cur != nil) {
if cur!.left != nil {
let pre = preNode(cur)!;
if pre.right === cur {
res.append(cur!.val)
cur = cur!.right
} else {
pre.right = cur
cur = cur!.left
}
} else {
res.append(cur!.val)
cur = cur!.right
}
}
return res
}
}

@eaststarpen 这种解法是为了达到循环不使用存储结构的目的。为什么要判断 cur->right == root,是因为我改了前驱节点的右指针指向，目的是为了判断 cur 的左子树是否遍历过。
代码中有一句判断是:
if (cur->left != nullptr) {
//.. .省略
} else {
pre->right = cur; // 这一句的目的是让前驱节点的右节点指向 cur ，方便后面遍历到前驱的时候，可以直接跳右节点调回去
cur = cur->left;
}

@mainjzb 比较离谱的是我把答案改成下面就能过了，只是在检测到前驱节点的右节点不为空的时候(说明此时左子树已全部遍历完毕)，加了一句`pre-right = nullptr;`把状态置回去，但是我总觉得这句没啥必要，因为我的 cur 节点很快就跳到右子树去了。
```
TreeNode *preNode(TreeNode *root) {
if (root == nullptr) return nullptr;
if (root->left == nullptr) return nullptr;
TreeNode *cur = root->left;
while (cur->right != nullptr) {
if (cur->right == root) {
break;
}
cur = cur->right;
}
return cur;
}

vector<int> inorderTraversal(TreeNode* root) {
if (root == nullptr) return {};
TreeNode *cur = root;
std::vector<int>res;

while (cur != nullptr) {
if (cur->left != nullptr) {
TreeNode *pre = preNode(cur);
if (pre->right != nullptr) {
pre->right = nullptr;
res.push_back(cur->val);
cur = cur->right;
} else {
pre->right = cur;
cur = cur->left;
}
} else {
res.push_back(cur->val);
cur = cur->right;
}
}

return res;
}
```
我一开始的解法自己在本地上跑也是没问题的，但是放到 leetcode 上就报上面的问题。
