[자료구조] Binary Tree Level Order Traversal
바이너리 트리 레벨선회 구현하기 Given a binary tree, return the level order traversal of its nodes’ values. (ie, from left to right, level by level). For example: Given binary tree [3,9,20,null,null,15,7], 3 /...
[자료구조] Binary Tree Postorder Traversal
바이너리 트리 후위선회 구현하기 Given a binary tree, return the postorder traversal of its nodes’ values. For example: Given binary tree [1,null,2,3], 1 \ 2 / 3 return [3,2,1]. Note: Recursive solution is trivial,...
[자료구조] Binary Tree Inorder Traversal
바이너리 트리 중위순회 구현하기 Given a binary tree, return the inorder traversal of its nodes’ values. For example: Given binary tree [1,null,2,3], 1 \ 2 / 3 return [1,3,2]. Note: Recursive solution is trivial, could...

[알고리즘] Search for a Range
asc로 정렬된 Integer배열에서 지정된 범위의 target Value를 찾아라 알고리즘의 복잡도는 O(log n)이어야 하며, target Value를 찾지 못하면 [-1, -1]을 반환한다. Given an array of integers sorted in ascending order, find...
