Introduction

Julia learns to stay in the contest and enjoys the hard work to solve some problems. Here is the status at 9:17pm 4/13/2017. Julia compared to the best performer.

Hackerrank Week code 31

It is not easy to  gain any point on advanced algorithm beyond medium algorithm on week of code contest. But Julia found out that she started to learn a few algorithms last 12 months. One of her favorite learning is binary index tree, so much up-and-downs feelings with the learning, but she wrote a very good question kindergarten adventures on code review website. She learned that she should not trust her feelings, it may seem to be difficult, but with calm and systematic way to handle the algorithm, use her strong data analysis experience, no algorithm should be hard. No mountain is too hard to conquer.
