@daytonellwanger Thanks! And best wishes to you :)

After updating vscode 1.64.0, this problem occurs on my macOS 11, then I disable `onBackpsace` and `onEnter` functionality, it works fine. Seems that 1.64.0 version update changes something to slow...

I made a long list of broken links, so I open a new issue #17599 to discuss.

> I think we need a broken links sensor to report and guard the condition. This is a great idea, I'll open an issue to discuss it in detail.

@MaXuSun 👍

@aristo-panhu 嗯，这确实是一个比较复杂的问题，所以我说递归改迭代是一个套路题，实际应用中不怎么会用到。非要利用左右子树的结果的话，需要把每次递归的返回值也存到栈里，这就是完全模拟计算机处理递归函数的过程了。

收到，已修正

@xiaozhi007 是的，我觉得关键是思路，思路掌握了随便你怎么写代码。

@chenguo-design 你说得对，感谢指正
