Calcule la mediana a partir de valores dados de media y moda

Dados dos enteros , la media y la moda , que representan la media y la moda de un grupo aleatorio de datos, la tarea es calcular la mediana de ese grupo de datos .

Entrada: media = 3, moda = 6
Salida: 4

Entrada: media = 1, moda = 1
Salida : 1

Enfoque: el problema dado se puede resolver usando la relación matemática entre la media , la moda y la mediana del grupo de datos. A continuación se muestra la relación entre ellos:

=> 

=> 

Por lo tanto, la idea es usar la fórmula anterior para encontrar la mediana de los datos cuando se dan la media y la moda.

A continuación se muestra la implementación del enfoque anterior:

// C++ program for the above approach
 
#include <bits/stdc++.h>
using namespace std;
 
// Function to find the median of a
// group of data with given mean and mode
void findMedian(int Mean, int Mode)
{
    // Calculate the median
    double Median = (2 * Mean + Mode) / 3.0;
 
    // Print the median
    cout << Median;
}
 
// Driver Code
int main()
{
    int mode = 6, mean = 3;
    findMedian(mean, mode);
 
    return 0;
}

// Java program for the above approach
import java.util.*;
 
class GFG{
 
// Function to find the median of a
// group of data with given mean and mode

{
     
    // Calculate the median
    double Median = (2 * Mean + Mode) / 3.0;
  
    // Print the median
    System.out.print((int)Median);
}
 
// Driver code
public static void main (String[] args)
{
    int mode = 6, mean = 3;
     
    findMedian(mean, mode);
}
