Java Algorithms: Coding a Binary Tree Right Side View (LeetCode)
Too Long; Didn't ReadGiven the root of a binary tree, imagine yourself standing on the right side of it. Then, return the values of the nodes you can see ordered from top to bottom. I would say it’s a pretty popular question during coding interviews Using simple words — think of the level for a particular node in a binary tree as the depth of that node. This code gives us linear time and space complexity, and it performs pretty well.
