LeetCode Time Tracker 作者： sjp

The 10,000 hour rule holds that mastery takes roughly ten thousand hours of deliberate practice. Nobody becomes a master of algorithms by reading about them. You get there by sitting down and grinding through problems, over and over, for years.
This extension counts those hours so you do not have to.
Open a LeetCode problem and the clock starts. Switch tabs, close the window, or get up and walk away, and it stops. There is no button to press. After a few months the total is an honest record of the work you actually did, rather than the work you remember doing.
