In a binary tree, the root node is at depth0, and children of each depthknode are at depthk+1. Two nodes of a binary tree arecousinsif they have the same depth, but have different parents. We are given therootof a binary tree with unique values, and the valuesxandyof two different...
From the definition of a cousin in a tree, we can achieve the solution. The first thing is both the nodes need to be at the same level. So, here comes the level order traversal to determine the levels of the nodes to check. Secondly, we need to check whether the nodes have the sam...
Sobald die Ebene gefunden ist, drucken Sie alle Knoten, die in dieser Ebene vorhanden sind, die kein gleichgeordnetes Element des Knotens oder des Knotens selbst ist. Es folgt die Implementierung des obigen Ansatzes in C++, Java und Python: C++ Java Python 1 2 3 4 5 6 7 8 9 10 ...
In a binary tree, the root node is at depth 0, and children of each depth k node are at depth k+1. Two nodes of a binary tree are cousins if they have the same depth, but have different parents. We are given the root of a binary tree with unique values, and the values x and...
