I disagree with "shortest runtime == best", in general. Legibility and maintainability are often more important. Runtime (and memory space) optimizations can be important in some cases, but you need to have a look where it makes most sense and try to avoid premature optimization.

yes shortest is not the best, but the code that executes the fastest is the best and this code is the least time taken to execute, so yeah,its the best ;)

Shortest != best

it's cool but still very resource intensive

Spoiler flags!
