穷举大法好

#include<bits/stdc++.h>
using namespace std;
int main()
{
	int x,y,z,sum=0;
	for(int z=1;z<=58;z++)
	{
		for(int y=z;y<=59;y++)
		{
			for(int x=y;x<=60;x++)
			{
				if(z*z*(y*y+x*x)==y*y*x*x)cout<<y<<" "<<x<<" "<<z<<endl;
			}
		}
	}
}

#include <bits/stdc++.h> #include<cmath> using namespace std;

int main() { for (double i=2.0;i<=60;i++){ for(double j=60.0;j>=i;j--){ for (double h=1.0;h<=i;h++){ if(abs(1.0/i/i+1.0/j/j-1.0/h/h)<=0.00000000001){ cout<<i<<" "; cout<<j<<" "; cout<<h<<endl; } } } }

return 0;
