Hello Everybody, I was beginning to learn segment tree but the problems on various judges seemed to be too non-trivial.I stumbled across the article from emaxx.ru (here : e-maxx.ru/algo/segment_tree).This site explains most of the non-trivial segment tree approaches and can be used to develop a sound understanding of the subject. But I'm not a Russian speaker and the Google Translate and Yandex Translate don't work well. There's a repository on github (here) but it does'nt contain the segment tree post.

It would be really great if some russian friend(s) could translate the segment tree post and maybe other posts.

Please do let me know your opinion.
