Breadth First Traversal
Feb 10, 2021
In breadth first traversal, each node is visited along with all other nodes in same level. Starting from node where there is only one node, the traversal then moves to it children. Both the children of the root node are processed.
Once the processing of 23, and 678 is completed, the the children of those nodes will be traversed from left to right. These are 12, 46, 461 and 789 in that order. Once these are done, the children of these 4 nodes are traversed, however as the nodes 12, 461, and 789 doesn’t have any children only 35 and 89 gets processed next.
I have written an in-depth article on how to solve traverse a binary tree in breadth first order programmatically.
