From January 2015, she started to practice leetcode questions; she trains herself to stay focus, develops "muscle" memory when she practices those questions one by one.
2015年初, Julia开始参与做Leetcode, 开通自己第一个博客. 刷Leet code的题目, 她看了很多的代码, 每个人那学一点, 也开通Github, 发表自己的代码, 尝试写自己的一些体会.
She learns from her favorite sports – tennis, 10,000 serves practice builds up good memory for a great serve. Just keep going.
Hard work beats talent when talent fails to work hard.

Leetcode 54: Spiral Matrix
Sept. 3, 2017
It is the classical medium level algorithm to write spiral matrix in one dimensional array. I have practiced more than 3 times. The key idea is to go over the four iterations from top row, last column, last row and first column, edge cases are one row or one column. last row and first column is optional because they are handled only if there are more than one row or more than two columns.
