That's how the pointer moves:

x = 0; y = 0
x = 1; y = 0
x = 2; y = 0
x = 3; y = 0
x = 3; y = 1
x = 4; y = 1
x = 4; y = 2
x = 4; y = 3
x = 3; y = 3
x = 2; y = 3
x = 1; y = 3
x = 0; y = 3
x = 0; y = 2
x = 0; y = 1
x = 1; y = 1
x = 2; y = 1
x = 3; y = 1
x = 4; y = 1
x = 4; y = 2
x = 4; y = 3
x = 3; y = 3
x = 2; y = 3
x = 1; y = 3
x = 0; y = 3
x = 0; y = 2
x = 0; y = 1
x = 1; y = 1
x = 2; y = 1
x = 3; y = 1
x = 4; y = 1
x = 4; y = 2
x = 4; y = 3
x = 3; y = 3
x = 2; y = 3
x = 1; y = 3
x = 0; y = 3
x = 0; y = 2
x = 0; y = 1
x = 1; y = 1
x = 2; y = 1
x = 3; y = 1
x = 4; y = 1
x = 4; y = 0
