Perfect Cubes(枚举) - TOJ 1945

题目描述

求出所有的{a,b,c,d}，符合1<=a<=200,b>=1,c>=1,d>=1且按照升序输出所有的组合。

列如，{6，3，4，5}的输出格式为Cube = 6，Triple = (3，4，5)

输出

Cube = 6， Triple = {3，4，5}

Cube = 12, Triple = {6，8，10}

{
for (d = 5;d < a;d++)
{
if (a*a*a == b*b*b + c*c*c + d*d*d&&b < c&&b < d&&c < d)
cout << "Cube = " << a << ", Triple = (" << b << "," << c << "," << d << ")" << endl;
