Write a function travel which takes a tuple of two coordinates; a starting location on a grid .x, and a starting location on a grid y. Your function should return a string of direction North, South, East, or West prompting if the defined coordinates belong to which moving direction. tuple that indicates the new position after following the directions starting from the given x, y. The returned string should be in the format '(x_new, y_new)'. The directions string will use 'N' to indicate increasing the y-coordinate, 'E' to indicate increasing the x-coordinate, 'S' to indicate decreasing the y-coordinate, and 'W' to indicate decreasing the x-coordinate. The case of the characters should be ignored. Any characters that are not 'N', 'E', 'W', or 'S' (ignoring letter-casing) should be ignored. 3 travel ('NWlewnw', 1, 2) # '(-1, 4)' 4 # 'N', (1, 2) => (1,3) (1,3) => (0,3) ignored (0, 3) => (1,3) 5 # 'W', 6 # '!', 7 # 'e', 8 # 'w', 9 # 'n', 10 # 'W', (1,3) => (0,3) (0,3) => (0,4) (0,4) => (-1,4) Quadrant II (-+) Quadrant III y-axis Quadrant I (+,+) Quadrant IV x-axis
