Lena was building a small utility to help Mark compare two different versions of a project’s organizational chart to see if they were exactly alike. Eva requested that the check be thorough, ensuring that every branch and every label matches its counterpart in both position and value. The tool needs to confirm that the entire layout is a perfect mirror image of the original. For example, if one chart has a 'Management' group on the left and a 'Staff' group on the right, but the second chart has those positions swapped, the utility should report that the two structures are not identical.
