既是正方形又是立方体的第 N 个数
给定一个数 n，求第 n 个数，它既是正方形又是立方体。前几个这样的数字是 1，64，729…
示例:
Input : 3
Output :729
729 is square of 27 and cube of 3.
Input :5
Output :15625
想法很简单，第 n 个这样的数字是 n 6
C++
// C++ program to find n-th number which is both
// square and cube.
#include <bits/stdc++.h>
using namespace std;
int nthSquareCube(int n)
{
return n*n*n*n*n*n;
}
// Driver code
int main()
{
int n = 5;
cout << nthSquareCube(n);
return 0;
}
