Yes, but all of those have impact to the actual function and performance of the proposed solution. By doing so, you are changing the solution.

Look at FizzBuzz. If you were to set strict requirements on performance (and allow for reiterative testing), the results from different groups of people would be identical. They would reach the same conclusion because that's how code works, it's far more aligned to math than it is creative writing.

So you cannot take an existing code solution and translate it to your own style. You are altering the program, the efficiency, and therefore the solution itself. Even when you do something like changing 1 single variable name!
