N-th number which is both a square and a cube

Given a number n, find the n-th number which is both a square and a cube. First few such numbers are 1, 64, 729, …

Examples :

Input : 3
Output :729
        729 is square of 27 and cube of 3.
Input :5
Output :15625

The idea is simple, n-th such number is n⁶

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;
}

Java

// Java program to find n-th number
// which is both square and cube.
import java.io.*;

public class GFG {

    static int nthSquareCube(int n)
    {
        return n * n * n * n * n * n;
    }

    // Driver code
    public static void main(String[] args)
    {
        int n = 5;

        System.out.println(nthSquareCube(n));
    }
}
