[Math] leetcode 1041 Robot Bounded In Circle problem:https://leetcode.com/problems/robot-bounded-in-circle/ As the hint mentions, we can keep track of the robot's position, when it finally return to the original position, or its direction is changed( no longer facing north), we can ...
https://leetcode.com/problems/robot-bounded-in-circle/discuss/731267/Easy-JAVA-Accepted-Solution 有circle条件:走一圈停在0,0,或者最后方向变了。 初始化(0, 0),dir 1,2,3,4代表N,W,S,E, 对应的方向是L时+1,R时-1 最后判断条件。
1041. Robot Bounded In Circle 本题题意: 一开始一个机器人站在了(0,0)上,面朝的方向是北,收到三个序列G,L,R。 G:直走 L:向左转 R:向右转 按序执行,永远重复。 返回TRUE,如果处在一个圈。 第一个卡住的点: 1.疑惑于机器人会不会不经过原点,然后还会出现一个圈?
1041. Robot Bounded In Circle (M) Robot Bounded In Circle (M) 题目 On an infinite plane, a robot initially stands at(0, 0)and faces north. The robot can receive one of three instructions: "G": go straight 1 unit; "L": turn 90 degrees to the left;...
