暴力枚举也不会超时

#include<bits/stdc++.h>
#define ll long long
int n;
int main(){
    std::cin>>n;
    for(int i=2;i<=n;i++){
        for(int j=2;j<=n;j++){
            for(int x=j;x<=n;x++){
                for(int y=x;y<=n;y++){
                    if(i*i*i==(j*j*j+x*x*x+y*y*y)){
                        std::cout<<"Cube = "<<i<<", Triple = (";
                        std::cout<<j<<','<<x<<','<<y<<")"<<std::endl;
                        continue;
                    }
                }
            }
        }
    }
    return 0;
}
