Initially, there is a Robot at position (0, 0). Given a sequence of its moves, judge if this robot makes a circle, which means it moves back to the original place.

The move sequence is represented by a string. And each move is represent by a character. The valid robot moves are R (Right), L(Left), U

(Up) and D (down). The output should be true or false representing whether the robot makes a circle.

Example 1:

Input: "UD"
