Question

Write a program in python to store two numbers. Find which number is greater. (Include "or"/"and"/"not"&comparison operators in the solution)

Answer 1

Explanation:

The idea is to use XOR operator. XOR of two numbers is 0 if the numbers are same, otherwise non-zero.

C++

// C++ program to check if two numbers

// are equal without using arithmetic

// and comparison operators

#include <iostream>

using namespace std;

  

// Function to check if two

// numbers are equal using

// XOR operator

void areSame(int a, int b)

{

    if (a ^ b)

        cout << "Not Same";

    else

        cout << "Same";

}

  

// Driver Code

int main()

{

  

    // Calling function

    areSame(10, 20);

}

JavaPython 3C#PHP

Output :Not Same

Method 2 : Here idea is using complement ( ~ ) and bit-wise ‘&’ operator.

C++

// C++ program to check if two numbers

// are equal without using arithmetic

// and comparison operators

#include <iostream>

using namespace std;

  

// Function to check if two

// numbers are equal using

// using ~ complement and & operator.

void areSame(int a, int b)

{

    if ((a & ~b) == 0 && (~a & b) == 0)

        cout << "Same";

    else

        cout << "Not Same";

}

// Driver Code

int main()

{
