Hi all,

I really enjoy leetcode.
My main question is: In leetcode there is a histogram about how many people i bet in running time. In order to be in the 10 best percentages i need sometimes to resort to tricks like using and modifying input variables which is a very bad practice especially in a threaded environment. I know that leetcode has no way to measure the quality of the code but i would like to hear from other leetcoders how they balance between running time and best practices.

Thanks
