In the algorithm section I am here going to share how to get the left view of the binary tree. For that you must know what is binary tree. Algorithms: Left view of a binary tree. Binary tree are the tree where one node can have only two child and cannot have more than two.
After a long time I took a look in algorithms and data structure and what I wrote first in Binary Tree and its different traversal in C++. I have never written them in python so I tried to write one. And yes writing them down in python is lot more easier. So lets me first introduce
