# 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 5DOWN 3LEFT 3RIGHT 2Â¡Â­The 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. import mathpos = [0,0]while True:    s = raw_input()    if not s:        break    movement = s.split(" ")    direction = movement[0]    steps = int(movement[1])    if direction=="UP":        pos[0]+=steps    elif direction=="DOWN":        pos[0]-=steps    elif direction=="LEFT":        pos[1]-=steps    elif direction=="RIGHT":        pos[1]+=steps    else:        passprint int(round(math.sqrt(pos[1]**2+pos[0]**2)))
