657. Judge Route Circle
- 描述:
题目很简单,就是判断路线能否组成一圈。向“右”走的步数一定要等于向“左”走的步数;向“下”走的步数一定要等于向“上”走的步数。 - 思路:
思路就是判断下字符串中“R”的个数是否等于“L”的个数,“D”和“U”同理 - 代码
class Solution(object): def judgeCircle(self, moves): """ :type moves: str :rtype: bool """ return moves.count('R')==moves.count('L') and moves.count('D')==moves.count('U')
