📅  最后修改于: 2021-10-23 08:56:36             🧑  作者: Mango

这里给出的是边长为a的立方体,任务是找到可以在其内切的最大领域。
例子:

Input: a = 4
Output: 2

Input: a = 5
Output: 2.5

方法

下面是上述方法的实现:

C++
// C++ Program to find the biggest sphere
// inscribed within a cube
#include 
using namespace std;
 
// Function to find the radius of the sphere
float sphere(float a)
{
 
    // side cannot be negative
    if (a < 0)
        return -1;
 
    // radius of the sphere
    float r = a / 2;
 
    return r;
}
 
// Driver code
int main()
{
    float a = 5;
    cout << sphere(a) << endl;
 
    return 0;
}


Java
// Java Program to find the biggest sphere
// inscribed within a cube
 
class GFG{
// Function to find the radius of the sphere
static float sphere(float a)
{
 
    // side cannot be negative
    if (a < 0)
        return -1;
 
    // radius of the sphere
    float r = a / 2;
 
    return r;
}
 
// Driver code
public static void main(String[] args)
{
    float a = 5;
    System.out.println(sphere(a));
 
}
}

Python3
# Python 3 Program to find the biggest
# sphere inscribed within a cube
 
# Function to find the radius
# of the sphere
def sphere(a):
     
    # side cannot be negative
    if (a < 0):
        return -1
 
    # radius of the sphere
    r = a / 2
 
    return r
 
# Driver code
if __name__ == '__main__':
    a = 5
    print(sphere(a))

C#
// C# Program to find the biggest
// sphere inscribed within a cube
using System;
 
class GFG
{
// Function to find the radius
// of the sphere
static float sphere(float a)
{
 
    // side cannot be negative
    if (a < 0)
        return -1;
 
    // radius of the sphere
    float r = a / 2;
 
    return r;
}
 
// Driver code
static public void Main ()
{
    float a = 5;
    Console.WriteLine(sphere(a));
}
}
