Just make hash with `#C8763`

```
def max_points(points)
return points.length if points.length < 3
end_index = points.length - 1
global_max = 0
(0...end_index).each do |i|
p = points[i]
dict = {}
same_count = 0
((i+1)..end_index).each do |j|
q = points[j]
if same_point(p, q)
same_count += 1
else
line = line_hash(p, q)
dict[line] = 1 if not dict[line]
dict[line] += 1
end
end
max = dict.reduce(1) { |m, (k, v)| m = v > m ? v : m }
max += same_count
global_max = max > global_max ? max : global_max
end
global_max
end
K1, K2, K3, K4 = 58763, 138763, 148763, 258763
def line_hash(p, q)
# ax + by = c
xd = p.x - q.x
yd = p.y - q.y
if xd == 0
K3 * p.x
elsif yd == 0
K4 * p.y
else
xd, yd = -xd, -yd if yd < 0
g = yd.gcd(xd)
a, b = yd / g, xd / g
c = a * p.x + b * p.y
a + K1 * b + K2 * c
end
end
def same_point(p, q)
p.x == q.x && p.y == q.y
end
```
