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.

Cohen & Steers Real Estate Securities Fund, Inc. Class Institutional CSDIX
Here is the link. The fund link on morningstar is here.
It is one of my 401 K par tech fund. I just could not believe that $10,000 dollars in 2009, now it worths more than $60,000 dollars.
Real Estate is a cyclical industry that is sensitive to interest rates, economic conditions (both nationally and locally), property tax rates, and other factors. Changes in real estate values or economic downturns can have a significant negative effect on issuers in the real estate industry. Stock markets are volatile and can decline significantly in response to adverse issuer, political, regulatory, market, economic or other developments. These risks may be magnified in foreign markets. Sector funds can be more volatile because of their narrow concentration in a specific industry. In general the bond market is volatile, and fixed income securities carry interest rate risk. (As interest rates rise, bond prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities.) Fixed income securities also carry inflation risk and credit and default risks for both issuers and counterparties. Unlike individual bonds, most bond funds do not have a maturity date, so avoiding losses caused by price volatility by holding them until maturity is not possible. Additional risk information for this product may be found in the prospectus or other product materials, if available.
Short Term Redemption Fee
None
Who May Want To Invest
Someone who is willing to accept the potentially lower diversification and higher risks associated with investing in a particular industry or sector.
Someone who is seeking to complement his or her core holdings with investments concentrated in a particular sector or industry.

There are so many problems for me to look into after 3 day algorithm practice. I have issues with basic loops writing, stack data structure, graph algorithm, and also all kinds of issues.
It is not easy to advance myself in terms of weekly contest ranking. One thing I can do is to solve more algorithms on Leetcode.com.
One idea is to solve two mock interview algorithm on Leetcode.com every day.

Case study: online code assessment preparation
April 26, 2019
It is so challenging for me to prepare online code assessment. I have to push myself hard to prepare, one idea is to work on mock interview on Leetcode.com.
Here are the algorithms I worked on from April 18 to April 22, 2019. I worked on a few random set algorithms, one mock interview I solved two algorithm, second one I did not solve any of those two. I was so surprised to learn the fact that I need to work hard and quickly master those basic algorithms again.
I chose to use those mock interview algorithms to test my problem solving status. I had chance to use those 38 algorithms to help me prepare for online assessment.
Total random set number is 28. I exhausted all random set algorithm in the first two categories, online assessment and phone interview.

In order to prepare Microsoft online code assessment on April 23, I went over over 20 random set mock interview algorithms on Leetcode.com. I stuck on a few algorithms, easy medium and hard level.
The preparation is also helpful for me to improve my weekly contest performance.
I do not have time to write code for every algorithm. I just choose to spend 5 to 10 minutes and see if I can come out the idea how to solve the problem. And then I terminate the interview and quickly look up the algorithm and solution on Leetcode.com
I put together a github page called online assessment preparation.
Here are the random set with algorithms I worked on.
I use over 15 set algorithms to prepare myself to work on various algorithms.

If there is no more investment from 2009 to 2012, it will take 4 years to recover the loss.

How to train myself daily on algorithm?

It is hard for me to come out the idea how to train myself daily. I took a long break from Nov. 2018 to March 2019 since I chose to work on personal finance research. I like to come back to work on algorithm and data structure problem solving daily. What are good ideas to work on.
One of ideas is to work on Leetcode.com mock interview code screen, real company, and onsite interview. I exhausted all options for code screen, real company; I did work on a few mock interview and real company, and then later I just use them to train myself thinking process, can I come out optimal solution to solve the problem?
It works very well, since I found out that I stuck on a few algorithm from study from April 18 to 22, 2019..
