Нужно перевести код с C++ на Python #include
using namespace std;
int a[100][100];main()
{
freopen("input.txt","r",stdin);
int w,h,n,i,j,k,x1,y1,x2,y2,s=0;
cin>>w>>h>>n;
for(i=0;i{
cin>>x1>>y1>>x2>>y2;
for(j=x1;jif(a[j][k]==0){s++;a[j][k]=1;}}
cout<}

x + y = 4 (2)

rearrange (2) to y = 4 - x (could do x = 4 - y )

substitute y = 4 - x into (1)

hence:  

x

2

+

(

−

x

⇒

x

and

⇒

x

−

x

=

0

factor and solve : 2x(x - 4 ) = 0  

⇒

x

=

0

,

x

=

4

substitute these values into y = 4 - x , to find corresponding values of y.

x = 0 : y = 4 - 0 = 4 → (0 , 4)

x = 4 : y = 4 - 4 = 0 → (4 , 0 )

These are the points of intersection with the line x +y = 4 and the circle
