Check if Two Nodes are Cousins in a Binary Tree Java Code - https://webrewrite.com/cousins-in-bin...

Given two values x and y, we have to write a code to check the nodes corresponding to values x and y are cousins or not. All the values in this binary tree are unique.

Two nodes of a binary tree are cousins if they have the same depth, but have different parents.

In a binary tree, the root node is at depth 0, and children of each depth k node are at depth k+1.

This problem is LeetCode Problem 169 known as Cousins in Binary Tree.
