men paskallni yaxshi tushunmiyman C++ da kod quyidagicha yozilgan:

#include<iostream>
using namespace std;
int main()
{
int n,m,s1=0,s2=0,i=0;
cin>>n>>m;
while(i==0)
{
if(n%2==0||m%2==0)
{
if(n%2==0&&m%2==0)
{
if(n>m)n=n/2;
else m=m/2;
}
else if(n%2==0)n=n/2;
else m=m/2;
s1+=n*m;
}
else
{
s1+=1;
s2+=n*m-1;
n=0;m=0;i=1;
