Update v1.2.2 to the lastest

#1

I bought v1.2.2 from Amazon before. Do you provider the difference between v1.2 and v1.4? I see the TOC but not the actual new content for v1.4.

Hey Jerry,

First of all, thanks for your question. The main difference between 1.2 and 1.3 is adding hints for all problems, and the difference between 1.3 and 1.4 is removing unnecessary hard problems to fit what is more likely to appear in a real interview. Sorry that we don’t have the update between 1.3 and 1.4 but the update between 1.2 and 1.3 can be found at https://docs.google.com/file/d/0B5znOthff2H-UTRYVmJpUW5EOEk/edit. Please take a look of that and feel free to reach us if you have any problem.

Again, thanks for your time to reach us about the problem of your EPI.
