Given the following C code and unoptimized assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
char buf[25000],out[10];
i;
X,Y,Z;
k;
p;
n;
main()
{
	n=read(0,buf,25000);
	while(buf[i++]-' ');
	while(buf[i++]-' ');
	for(;;)
	{
		k=buf[i++];
		if(k<'0')break;
		X=X*10+k-'0';
	}
	--n;--n;
	p=1;
	for(;;)
	{
		k=buf[n--];
		if(k<'0')break;
		Z+=p*(k-'0');
		p*=10;
	}
	p=1;
	for(;;)
	{
		k=buf[n--];
		if(k<'0')break;
		Y+=p*(k-'0');
		p*=10;
	}
	X-=Z;if(X<0)X=-X;
	Y-=Z;if(Y<0)Y=-Y;
	if(X<Y)X=Y;
	i=9;
	do{
		out[--i]=X%10+'0';
		X/=10;
	}while(X);
	write(1,out+i,9-i);
}```

Given the following C code and unoptimized assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c

k;
p;
n;
main()
{
	n=read(0,buf,25000);
	while(buf[i++]-' ');
	while(buf[i++]-' ');
	for(;;)
