HackerRank - OpenBracket CodeSprint

Oct. 15, 2016

The Saturday and Sunday (Oct. 15 - Oct. 16) are reserved for HackerRank OpenBracket CodeSprint.

Came back from the vacation trip (Sept. 29, 2016 - Oct. 14, 2016) from China on Oct. 14, 2016, Julia spent 2 days to rest at home to overcome jet lag, and also she was busy with algorithm problem solving.



Read blogs:
Julia values the contest - as a training, and also she likes to check leaderboad, and see what she can learn from others.

Julia's favorite new teaching approach:
"My teaching draws upon my research in data structures, algorithms, graph theory, optimization, statistics, geometry, numerical analysis, and parallel computing. Connecting these topics and enabling students to effectively utilize key ideas from them is one of my main teaching goals. These connections are often best motivated by key problems on the boundaries of these areas. Solving such problems usually requires adapting various tools from these areas, leading to a deeper understanding of both the tools and the problems. For example, instead of presenting sorting algorithms and balanced search trees separately, I prefer to discuss applications that integrate them such as geometric plane sweep algorithms. I believe this problem oriented exposition is helpful for using the tools later on, as well as for moving towards open-ended exploration in an area."

"I also seek opportunities to interact with students in a wider range of academic activities. Having participated in outreach activities such as math and programming camps while in high school, I regularly volunteered for them after graduating. Since 2006, I’ve been involved with the USA Computing Olympiad, whose annual online competitions attract around two thousand participants from high schools worldwide."
