one test case failing. im checking no, of elements at each level

hi @akshatkaush, structurally identical means that there structure is same that is along with the number of elements to be same , the placement of elements (nodes) should also be the same i.e. if an there are two elements on the left of root in tree 1 than two elements must be on the left of root in tree 2 if they are structurally same .
In case of any doubt feel free to ask :slight_smile:
mark your doubt as resolved If you got the answer
