May LeetCoding Challenge #Day7 #Cousins in Binary Tree #Java (1) 썸네일형 리스트형 May LeetCoding Challenge[Day7] - Cousins in Binary Tree 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 y of two different nodes in the tree. Return true if and only if the nodes corresponding to the values x and y are cousins... 이전 1 다음
