If it works, is it right?

Boolean Algebra and Digital Logic Project 1


When doing the k-maps with 4 variables, I am getting a different expression due to different regrouping. As long as my expression works it would be considered right, right? Or do I need to have the same expression as the one listed? If so how do I know what way they will group?

What I’ve tried

For the screenshot provided I got F = x+ y’+ yz by grouping the last row together, then grouping the first two columns, and then grouping the last column.

But the solution they give is F = y’ + z + x and they got it by grouping the first two columns, then grouping the middle columns, and grouping the last row.

Would my answer be wrong or are they both right?
