* 核心思路：倒序单调栈（适配你的学习习惯），时间复杂度O(n)，空间复杂度O(n)
I used to strive to keep my hands on the keyboard and only use the mouse when necessary, but this customized mouse kind of flipped that paradigm for me. Now anything I would have used a keyboard shortcut for in the past, I can do from the mouse. I incorporated several shortcuts that were new to me and several I was familiar with, but could never quite remember. Now I don’t need to remember the right combination of modifiers and letters or arrows on the keyboard; it’s all laid out on my mouse’s six keys in a way that is very logical (at least to me). I can quickly Shift-click; Control-click; Enter; Backspace; Delete; Escape; Tab; Refresh; Undo or Redo; cut, copy, & paste; switch apps, tabs, & virtual desks; control media; and so much more, without navigating the right-click menu, all from my mouse thanks to my custom firmware.。关于这个话题，同城约会提供了深入分析
