consider the graph of the test case.
you notice that number of groups is max number of levels which will be 3 in this case because: level 1: nodes 1,5. level 2 : nodes 2,4. level 3 : nodes 3.
which will form groups in it there are not any superior of another in same group. to calculate answer you will use bfs algorithm for graph .
hope it well.
Thanks
