Why cant we have two or more answers as solution

Hi Maciej,

Thank you for your reply. I want to bring in my last question in the forum.

There were two ways suggested to solve my problem, and both of them are correct and have no priority over others. It happens a lot in coding that two different codes can give the same result.
To avoid confusion, we can have solutions 1, 2 to 3. When someone chooses one post as a solution, there can be allowed to choose up to two more posts as alternative solutions.
