Final Position of the Robot

You are given a string cmd consisting of characters 'U', 'D', 'L', and 'R' which represent movements of a robot: up, down, left, and right respectively. Your task is to compute the final position \( (x, y) \) of the robot after executing all the commands.

The moves are defined as follows:

• U: move up by 1 unit (i.e. \( y = y + 1 \))
• D: move down by 1 unit (i.e. \( y = y - 1 \))
• L: move left by 1 unit (i.e. \( x = x - 1 \))
• R: move right by 1 unit (i.e. \( x = x + 1 \))

For example:

Input: UDLR
Output: 0 0

Write a program that reads a command string from stdin and prints the final coordinates to stdout separated by a space.

inputFormat

The input is a single line containing a string cmd which represents the series of commands. It contains only the characters 'U', 'D', 'L', and 'R'.

outputFormat

Output two integers separated by a space, representing the final x and y coordinates of the robot after executing the commands.
