HackerRank - week of code 28

January 12, 2016

Introduction
Julia did some research by reading the article written by Dr. Patrick Cohn about tennis match performance and training, the article "Tennis Psychology: Practice Confidence vs. Match Confidence", she learned a few things. Here are her favorite quotes:

-----  great thoughts about tennis sports  - coding should also be the same  ---------

Let’s start by answering a basic question: What does it mean to play with trust? When you play with trust, you allow yourself to play freely – you have faith in your practice. You don’t grind on your technique or over coach yourself in matches because you are confident that you can rely on your practice. You just react to the ball, knowing your training will carry you.

Through practice and repetition – a lot of it – your body learns how to hit shots effortlessly, instinctively. Meaning with enough repetition and practice, you can hit shots without thinking about how to hit shots. You should think of competition as a “closed book test” to use a schoolwork analogy. You’ve studied (practiced) for the test. In competition, it’s time to trust what you studied. 

How does your trust break down all of a sudden when you play in a match? Many mental game or tennis issues can affect your level of trust in matches. A lack of confidence and cause your trust to not show up. Indecision is another barrier to trust. Fear of failure can kill the soundest strokes. Perfectionism can cause you to focus too much on perfect strokes and not enough on strategy and playing smart shots.

What can players do to improve their trust in matches?
Trust starts with having a balance in your practice routines. Practicing the right way will help you improve your trust in matches. The key is to practice like you compete.

Practice is getting better. 

So, Julia learns a few things here: 
notes will be written here later. 

She understands that it is very important for her to put herself on stress training daily, therefore, she did work on the week of code 28 so patiently, specially on the algorithm "Lucky Number Eight". She still likes to write a recursion function and review her favorite study blog written in less than 2 months - Nov. 24, 2016.

So far, she ranked 1480 out of 9215 on January 12, 2017, 11:23pm

One of Google employee cui aoxiang - performance unbelievable. She just kept finding new faces from Google, facebook, and also extraordinary performance. Next time, study her code and post some thoughts here.
