【leetcode】机器人能否返回原点 c++

题目描述：在二维平面上，有一个机器人从原点 (0, 0) 开始。给出它的移动顺序，判断这个机器人在完成移动后是否在 (0, 0) 处结束。移动顺序由字符串表示。字符 move[i] 表示其第 i 次移动。机器人的有效动作有 R（右），L（左），U（上）和 D（下）。如果机器人在完成所有动作后返回原点，则返回 true

【ARC073D】Many Moves

传送门我竟然可以独立做出远古ARC的压轴题。我记得上一次做四题 ARC D 还是一道Hall定理+扫描线的神题。分析：首先你发现，假设我们已经处理完了前 \(i\) 个询问，则必须有一个棋子在 \(q_{i}\) 的位置。所以我们只关注另外一个棋子的位置，设 \(f_{i,j}\) 是前 \(i\) 轮，另外一个棋子

C. Board Moves（递推）

题意：有一个n*n的方格图，每个格子可以向周围8个方向移动，一次只能移动一步，最后要让所有的格子都移动到中间格子，问要多少步才能实现目标。题解：自己画的图：当n=1时，只有中间一个小格，所以不需要移动，答案为0。当n=3时，就要让橙色那一圈方格都移到中间，八个方格移动的步
