Whoa, I appreciate the sneak peek PDF and response! CCTI was my first book I bought for grinding software engineer interviews. I’ll definitely revisit whether to get the new version after reading the first 9 chapters!
The book also has a discord server (link in the free PDF!), so if you have other questions, feel free to ping me there with them! We are about to start the weekly leetcode contest, and there will be a write-up after it finishes on which techniques and templates we've used from the book, which might give you more of a sense of how different it is. Hope to see you there, my friend!
