'''
A robot moves in a plane starting from the original point (0,0).
The robot can move toward UP, DOWN, LEFT and RIGHT with a given steps.
The trace of robot movement is shown as the following:
	UP 5
	DOWN 3
	LEFT 3
	RIGHT 2
	¡¬
	The numbers after the direction are steps.
	Please write a program to compute the distance from current
	position after a sequence of movement and original point.
	If the distance is a float, then just print the nearest integer.
	Example:
	If the following tuples are given as input to the program:
	UP 5
	DOWN 3
	LEFT 3
	RIGHT 2
	Then, the output of the program should be:
	2
