用pow()很耗时间吗?//同样的代码,我如果用pow就超时,不用就ac,纳闷了???
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int max;
cin>>max;
int now=6;
while(now<=max)
{
for(int i=2;i<now;i++)
{
for(int j=i;j<now;j++)
{
for(int k=j;k<now;k++)
{
if(now*now*now==(i*i*i+j*j*j+k*k*k))
// if(pow(now,3)==(pow(i,3)+pow(j,3)+pow(k,3)))
cout<<"Cube = "<<now<<", Triple = ("<<i<<","<<j<<","<<k<<")"<<endl;
}
}
}
now++;
}
return 0;
}
