In the lecture about Rectangle.asm, the loop is implemented as such:
@0
D=M
@n
M=D
@i
M=0
(LOOP)
@i
D=M
@n
D=D-M
@END
D;JGT
Let's assume n (user input in R0) is 10, then when the terminating condition is met, which is i-n=i-10>0, or i>10, we have already looped through i from 0..10; in other words, before terminating the loop, we have eleven is:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
In such a case, we draw 11 lines rather than 10 lines.
My thought is that here it should be
@END
D;JEQ
just like the previous example before Rectangle.asm.
Please kindly advise if I missed or misunderstood anything. Thanks!
