Now quiz.child(0) is number of type M-C which has two child and child at 0 is Points and child at 1 is Parts
quiz.child(0).child(1) is Points and now further points doesn't have any children hence going further to quiz.child(0).child(1).child(0) is nothing hence it will not return anything.
Next quiz.child(1) is number of type coding and value is 5.
Size of the tree is (2^depth)-1
and here depth of tree is 3 hence size is (2^3)-1 i.e. 7
