문제 Given an n-ary tree, return the level order traversal of its nodes' values. Nary-Tree input serialization is represented in their level order traversal, each group of children is separated by the null value (See examples). n-ary 트리가 지정된 경우 해당 노드 값의 수준 순서 통과를 반환합니다. Nary-Tree 입력 직렬화는 레벨 순서 순회(traversal)로 표현되며, 각 자식 그룹은 null 값으로 구분됩니다(예제 참조). 예시 Example 1: Input: root = [1,null,3,2,4,null,5,6] ..

문제 Given two n x n binary matrices mat and target, return true if it is possible to make mat equal to target by rotating mat in 90-degree increments, or false otherwise. 두 개의 n x n 이진 행렬 매트와 타겟이 주어지면 매트를 90도 단위로 회전시켜 표적으로 동일하게 만들 수 있으면 true를 반환하고 그렇지 않으면 false를 반환합니다. 예시 Example 1: Input: mat = [[0,1],[1,0]], target = [[1,0],[0,1]] Output: true Explanation: We can rotate mat 90 degrees clockwise..

문제 You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the rotation. 이미지를 나타내는 n x n 2D 매트릭스가 제공되면 이미지를 90도(시계 방향) 회전합니다. 이미지는 제자리에서 회전해야 합니다. 즉, 입력 2D 매트릭스를 직접 수정해야 합니다. 다른 2D 매트릭스를 할당하지 않고 회전을 수행합니다. 예시 Exam..
