Problem
Write a function that will return the width of a linked binary tree, that is, the maximum number of nodes on the same level. traversal sequences For the following exercises, it is assumed that the data stored in the nodes of the binary trees are all distinct, but it is not assumed that the trees are binary search trees. That is, there is no necessary connection between any ordering of the data and their location in the trees. If a tree is traversed in a particular order, and each key is printed when its node is visited, the resulting sequence is called the sequence corresponding to that traversal.
