思路:
循环遍历,模拟即可
代码:
class Solution {public boolean judgeCircle(String moves) {int n = moves.length();if(n%2==1) return false;int x=0,y = 0;for(int i = 0;i<n;i++) {char c = moves.charAt(i);// if(c=='U') {// y++;// } else if(c=='D') {// y--;// } else if(c=='L') {// x--;// } else if(c=='R') {// x++;// }switch(c) {case'U':y++;break;case'D':y--;break;case'L':x--;break;case'R':x++;break;}}return x==0 && y==0;}
}
