HackerEarth: algorithm tutorial and problems

Sept. 26, 2016

Julia has some difficulty to handle medium, advanced, hard and difficult algorithm on HackerRank contest world code sprint, so she is actively seeking ways to improve.

Try this one - HackerEarth, at least read each algorithm and find typical problem sets; if need, she can quickly jump into the code. She tries to shorten the time from learning the algorithm to working out an algorithm in 8 hours. So she can compete in the contest.

It is hard to compete in the contest right now, to cover her weakness, she has to dedicate a lot of time for a medium level algorithm. She has to give up weekend sports activities, has to focus on the contest whole weekend, nonstop.

One algorithm a time. One contest a time.

It does not matter how hard Julia has to work on contest, at the end of day - more than 8 hours work, she has to be able to come out a solution for a medium algorithm on HackerRank contest.

The contest problem solving is very similar to the work environment; 48 hours is much better than 24 hours. Julia likes the challenges, she just likes to compete, also she thinks that it is very healthy to compete, so she can improve performance in short time. She could not learn these from the work.

HackerRank is very strict on scoring, therefore, Julia is pushed so hard to bring out her best talent, relentless trial and errors, patiently through 8 hours a time.
