Hackerrank Game of Two Stacks - in the contest

Feb. 19, 2017

Introduction



This is by far most challenge problem Julia has in last week, and she likes the difficult level of university codesprint. She understood that she should have more reasoning what she can do, after she made an effort to gain 10 points of maximum 30 points. 30% success rate tells that most of people did not push their analytical ability to the most, Julia could not believe that she can find optimal solution, but playing game is like a real life experience, define the rules, how to play against the rules to your best benefit. Play safe to get some points first, since Julia spent hours to debug the code for extreme test cases, then Julia ran short of time to think about the optimal solution.

In terms of growth mindset, how to grow from a 30% performance on first medium level today, in 3 months or 6 months, become a 60% or 100% performance on a first medium level? Recently, Julia did some study on this through sport performance coaching.

In the contest


Her C# submission only made 30% of maximum score, but she spent hours to make it best, learned the importance to avoid complicate code.
