File:Binary tree.svg Exercise: Binary Trees Create a binary tree for the following data input: 5, 2, 6, 8, 4, 1, 9, 7, 3 thumb|Sorted tree Create a binary tree for the following major city input: Monaco, Paris, Vatican, Rome, Norwich, Lewisham, New York, Partington thumb|sorted major global cities. This tree is very right heavy and if you continue Computer Science to University level you would be asked to find ways of balancing trees
