Code Performance Increase - How?

Question

I have a technical test on Codility tomorrow and currently practicing. Before any judgement, please keep in mind that I am a beginner still.

I have been doing a Demo test and I would get 3/4 passes at everything, but I get 0/4 at Code Performance and don't know why? Can anybody please advice me on what is code performance and what can I do to increase it through code choices?

I thought it doesn't matter what code you choose to write as long as you get the correct answer. Thank you!

Answer 1

Which language are you using?

Answer 2

It could refer to several things: most likely how long it takes for the code to run, possibly how much memory it uses, etc.

Answer 3

Maybe try to change type of images if you are using them, restructure your code to be more reusable

Answer 4

I am using C#. And I am trying to find ways for code performance to improve in my solutions.

Answer 5

Sorry, I'm not familiar with C

Answer 6

I've never used C#. Do an internet search for "C# performance tips".
