I’m using the EPI web-version using https://play.google.com/books, and preferred to use a PDF copy, but couldn’t find a way to do that.
So, I’m stuck with using EPI on the browser (only when internet is accessible), and the search-button on play.google.com/books doesn’t work very well when searching for text within the EPI book. Sometimes it gives wrong or NO Results even when text exists in the book.
I couldn’t find Segment trees through Search button in EPI. Are they covered anywhere? If so, which section/page and which release of EPI?
