Check whether a given number N is a Nude Number or not
  • Difficulty Level : Medium
  • Last Updated : 03 Mar, 2021

Given an integer N, the task is to check whether N is a Nude number or not.
 

A Nude number is a number that is divisible by all of its digits (which should be nonzero). 
 

Example: 
 

Input: N = 672 
Output: Yes 
Explanation: 
Since, 672 is divisible by all of its three digits 6, 7 and 2. Therefore the output is Yes.
Input: N = 450 
Output: No 
Explanation: 
Since, 450 is not divisible by 0 (Also it gives exception). Therefore the output is No. 
 

 



Approach: Extract digits from number one by one and check these two conditions: 
 

  1. The digit must be non-zero, to avoid exception
  2. And the digit must divide the number N

When both these condition is satisfied by all digits of N, then the number is called Nude number.
Below is the implementation of the above approach:
 

C++




// C++ program to check if the
// number if Nude number or not
 
#include <iostream>
using namespace std;
 
// Check if all digits
// of num divide num
bool checkDivisbility(int num)
{
    // array to store all digits
    // of the given number
    int digit;
    int N = num;
    while (num != 0) {
        digit = num % 10;
        num = num / 10;
 
        // If any of the condition
        // is true for any digit
        // Then N is not a nude number
        if (digit == 0 || N % digit != 0)
            return false;
    }
 
    return true;
}
 
// Driver code
int main()
{
    int N = 128;
 
    bool result = checkDivisbility(N);
    if (result)
        cout << "Yes";
    else
        cout << "No";
 
    return 0;
}

Java




// Java program to check if the
// number if Nude number or not
import java.util.*;
class GFG{
 
// Check if all digits
// of num divide num
static boolean checkDivisbility(int num)
{
    // array to store all digits
    // of the given number
    int digit;
    int N = num;
    while (num != 0)
    {
        digit = num % 10;
        num = num / 10;
 
        // If any of the condition
        // is true for any digit
        // Then N is not a nude number
        if (digit == 0 || N % digit != 0)
            return false;
    }
    return true;
}
 
// Driver code
public static void main(String[] args)
{
    int N = 128;
 
    boolean result = checkDivisbility(N);
    if (result)
        System.out.print("Yes");
    else
        System.out.print("No");
}
}
