N 的除数的几何平均值的整数部分

原文:https://www . geeksforgeeks . org/整数部分 n 的几何平均数/

给定一个整数 N ,任务是求 N 的除数的几何平均值的整数部分。几何平均值是一种特殊类型的平均值,我们将数字相乘,然后取平方根(对于两个数字)、立方根(对于三个数字)等等。

例: 输入: N = 4 输出:2 4 的除数为 1、2 和 4 几何平均数=(1 * 2 * 4)(1/3)= 8(1/3)= 2 输入: N = 16 输出: 8 除数

方法:可以观察到 N 的值会形成一个系列,如 1,1,1,2,2,2,2,2,3,3,3,3,3,3,3,3,3,3,…..nthT9【术语】为 ⌊√n⌋ 。 以下是上述方法的实施:

C++

// C++ implementation of the approach
#include <bits/stdc++.h>
using namespace std;

// Function to return the integer
// part of the geometric mean
// of the divisors of n
int geometricMean(int n)
{
    return sqrt(n);
}

// Driver code
int main()
{
    int n = 16;

    cout << geometricMean(n);

    return 0;
}

Java 语言(一种计算机语言,尤用于创建网站)

// Java implementation of the approach
class GFG
{

// Function to return the integer
// part of the geometric mean
// of the divisors of n
static int geometricMean(int n)
{
    return (int) Math.sqrt(n);
}

// Driver code
public static void main(String []args)
{
    int n = 16;
    System.out.println(geometricMean(n));
}
}

Python 3

# Python3 implementation of the approach
from math import sqrt

# Function to return the integer
# part of the geometric mean
# of the divisors of n
def geometricMean(n) :

    return int(sqrt(n));

# Driver code
if __name__ == "__main__" :

    n = 16;

    print(geometricMean(n));

C

// C# implementation of the approach
using System;   

class GFG
{

// Function to return the integer
// part of the geometric mean
// of the divisors of n
static int geometricMean(int n)
{
    return (int) Math.Sqrt(n);
}

// Driver code
public static void Main(String []args)
{
    int n = 16;
    Console.WriteLine(geometricMean(n));
}
}

<script>

// Javascript implementation of the approach

// Function to return the integer
// part of the geometric mean
// of the divisors of n
function geometricMean(n)
{
    return Math.sqrt(n);
}

// Driver code
var n = 16;
document.write(geometricMean(n));
