Robot Final Coordinates

Given a sequence of moves for a robot on a two-dimensional plane, determine its final coordinates. The robot starts at the origin (0,0) and follows the moves one by one. Each move is represented by a character: 'U' for up, 'D' for down, 'L' for left, and 'R' for right.

You can calculate the final coordinates using the formulas below:

$$ x = \text{number of R moves} - \text{number of L moves} $$

$$ y = \text{number of U moves} - \text{number of D moves} $$

Implement a program that reads the number of moves and the moves themselves from standard input, and outputs the final x and y coordinates to standard output.

inputFormat

The first line contains an integer N representing the number of moves.

The second line contains N space-separated characters, each of which is one of 'U', 'D', 'L', or 'R'.

outputFormat

Output the final coordinates of the robot as two integers x and y separated by a space.
