# There is a robot which can move around on a grid

Problem

There is a robot which can move around on a grid. The robot is placed at point (0,0). From (x, y) the robot can move to (x+1,

y), (x-1, y), (x, y+1), and (x, y-1). Some points are dangerous and contain EMP Mines. To know which points are safe, we check

whether the sum digits of abs(x) plus the sum of the digits of abs(y) are less than or equal to 23. For example, the point (59,

75) is not safe because 5 + 9 + 7 + 5 = 26, which is greater than 23. The point (-51, -7) is safe because 5 + 1 + 7 = 13, which is

less than 23.

How large is the area that the robot can access?

, i need documentation that contains for following

● Structure and style of the code

● Issues or bugs in the code

● Efficiency of the code

● How well you can explain your setup
