Check if a given binary tree is completed. A complete binary tree is one in which every level of the binary tree is completely filled except possibly the last level. Furthermore, all nodes are as far left as possible. Examples 5 / \ 3 8 / \ 1 4 is completed. 5 / \ 3 8 / \ ...

With respect of a given binary tree, our task is to determine if a given vertical level of the binary tree is sorted or not.(With respect of this case, when two nodes are overlapping, verify if they form a sorted sequence in the level they lie.)...
