Readability of the code or speed of its execution?

Question

Algorithms

Dear Khabrachans, please tell me, when writing a project, what should I pay more attention to, the readability of the code (if other programmers will work with it) or the speed of execution? The question is not only about the choice of recursion and cycles, but also in general, when writing any project.
That's where the question comes from: recursion is slower, but it's more readable than a loop, which is faster than recursion.

Answer 1

That's where the question comes from: recursion is slower, but it's more readable than a loop, which is faster than recursion.

Thank you, neighing)
Better - learn the operations of early exit from the "whirlwind" of recursion.
1. Code readability - determined by its architecture.
2. Speed ​​of execution - by a correctly chosen algorithm for a specific task and the number of operations for dynamic work with memory: memory allocation for objects, variables, etc.
