A plane starting from the original point (0,0).

It can move toward UP, DOWN, LEFT, and RIGHT with a given steps.

Please write a Python program using Manhattan distance formula to compute the distance from the current position after a sequence of movement and original point.

If the following movements obtained from the user input are given to the program:

UP 5

DOWN 3

LEFT 3

RIGHT 2

X

Then the output of the program should be: 3

Note: The numbers after the direction are steps. X means the end of movement.
