I was trying to write a solution to Advent of Code 2015 day 6 and I am getting a wring answer.

Can someone please help whats going wrong.

```
function solve()
path = pwd() * "/AoC/input.txt"
instructions = readlines(path)
lights = BitArray(zeros(1000,1000))
for i in instructions
if split(i," ")[1] == "turn"
start_x,start_y = map(x -> parse(Int64,x),split(split(i," ")[3],','))
end_x,end_y = map(x -> parse(Int64,x),split(split(i," ")[5],','))
start_x += 1
start_y += 1
end_y += 1
end_x += 1
if split(i," ")[2] == "on"
lights[start_x:start_y,end_x:end_y] .= 1
elseif split(i," ")[2] == "off"
lights[start_x:start_y,end_x:end_y] .= 0
end
elseif split(i," ")[1] == "toggle"
start_x,start_y = map(x -> parse(Int64,x),split(split(i," ")[2],','))
end_x,end_y = map(x -> parse(Int64,x),split(split(i," ")[4],','))
start_x += 1
start_y += 1
end_y += 1
end_x += 1
lights[start_x:start_y,end_x:end_y] = .!lights[start_x:start_y,end_x:end_y]
end
end
return sum(lights)
end
println(solve())
```

Also, I would like to know if there is better way to achieve the same task in more â€śjulia-wayâ€ť .

Thanks in advance.
