Python的哦~ 但是不知道哪里错了哦~

a,b,c,d=map(int,input().split())
z=a*b*c*d
ax=b*c*d
bx=a*c*d
cx=b*a*d
dx=b*c*a
ab=round(z/(ax+bx),2)
abcd=round(z/(ax+bx+cx+dx),2)
print("%.2f"%ab,"\n","%.2f"%abcd)

#include <iostream>
using namespace std;
double a,b,c,d,x1,x2;
int main(){
    cin>>a>>b>>c>>d;
    x1=1/(1/a+1/b);
    x2=1/(1/a+1/b+1/c+1/d);
    printf("%.2f",x1);
    cout<<endl;
    printf("%.2f",x2);
    return 0;
}

c++

a,b,c,d=map(int,input().split())

s=1

t1=s/(s/a+s/b)

t2=s/(s/a+s/b+s/c+s/d)

print("%.2f"%t1)

print("%.2f"%t2)

using namespace std;
int main()
{
	float a,b,c,d,t1,t2,s=1;
	cin>>a>>b>>c>>d;
	t1=s/(s/a+s/b);
	t2=s/(s/a+s/b+s/c+s/d);
	printf("%.2lf\n%.2lf",t1,t2);
