WebJul 7, 2014 · TIME COMPLEXITY. The time complexity of the algorithm is O (N^2), where ‘ N ’ is the total number of nodes in the tree. This is due to the fact that we traverse each node once (which will take O (N)), and for every leaf node we might have to store its path which will take O (N). We can calculate a tighter time complexity of O (NlogN) from ...
