Hello, CF community.
I am starting to write about algorithms for fun and to spread the knowledge. Please read my new article about sparse table – a cute data structure to find range minimums in an array:
P.S. A little bit about myself: I was active in the competitive programming a while ago, especially during my two ACM ICPC World Finals in 2014 and 2015. Currently, I am working for Google and trying to revive some old algorithms knowledge :)
