Bitwise Operations on Digits of a Number

Last Updated : 12 Jul, 2025

Given a number N, the task is to perform the bitwise operations on digits of the given number N. The bitwise operations include: 
 

  • Finding the XOR of all digits of the given number N
  • Finding the OR of all digits of the given number N
  • Finding the AND of all digits of the given number N


Examples: 
 

Input: N = 486
Output: 
XOR = 10
OR = 14
AND = 0

Input: N = 123456
Output: 
XOR = 10
OR = 14
AND = 0


 


Approach:
 

  1. Get the number 
     
  2. Find the digits of the number and store it in an array for computation purpose. 
     
  3. Now perform the various bitwise operations (XOR, OR, and AND) on this array one by one.


Below is the implementation of the above approach: 
 

C++ 
// C++ implementation of the approach

#include <bits/stdc++.h>
using namespace std;

int digit[100000];

// Function to find the digits
int findDigits(int n)
{
    int count = 0;

    while (n != 0) {

        digit[count] = n % 10;
        n = n / 10;
        ++count;
    }

    return count;
}

// Function to Find OR
// of all digits of a number
int OR_of_Digits(int n, int count)
{

    int ans = 0;

    for (int i = 0; i < count; i++) {
        // Find OR of all digits
        ans = ans | digit[i];
    }

    // return OR of digits
    return ans;
}

// Function to Find AND
// of all digits of a number
int AND_of_Digits(int n, int count)
{

    int ans = 0;

    for (int i = 0; i < count; i++) {
        // Find AND of all digits
        ans = ans & digit[i];
    }

    // return AND of digits
    return ans;
}

// Function to Find XOR
// of all digits of a number
int XOR_of_Digits(int n, int count)
{

    int ans = 0;

    for (int i = 0; i < count; i++) {
        // Find XOR of all digits
        ans = ans ^ digit[i];
    }

    // return XOR of digits
    return ans;
}

// Driver code
void bitwise_operation(int N)
{

    // Find and store all digits
    int countOfDigit = findDigits(N);

    // Find XOR of digits
    cout << "XOR = "
         << XOR_of_Digits(N, countOfDigit)
         << endl;

    // Find OR of digits
    cout << "OR = "
         << OR_of_Digits(N, countOfDigit)
         << endl;

    // Find AND of digits
    cout << "AND = "
         << AND_of_Digits(N, countOfDigit)
         << endl;
}

    return 0;
