The following are not allowed to use
- Comparison Operators
- String function
Examples:
Input : num1 = 1233, num2 =1233
Output : SameInput : num1 = 223, num2 = 233
Output : Not Same
Method 1: The idea is to use the XOR operator. XOR of two numbers is 0 if the numbers are the same, otherwise non-zero.
#include <iostream> using namespace std;
// Finds if a and b are same. void areSame( int a, int b)
{ if (a^b)
cout << "Not Same" ;
else
cout << "Same" ;
} int main()
{ areSame(10, 20);
} |
class GFG
{ // Finds if a and b are same
static void areSame( int a, int b)
{
if ( (a ^ b) != 0 )
System.out.println( "Not Same" );
else
System.out.println( "Same" );
}
public static void main(String args[])
{
areSame( 10 , 20 );
}
} // This code is contributed by Sumit Ghosh |
# Finds if a and b are same. def areSame(a, b):
if (a ^ b):
print ( "Not Same" )
else :
print ( "Same" )

// C# program to check if 2 // numbers are same using System;
class GFG
{ // Finds if a and b are same
static void areSame( int a, int b)
{
if ( (a ^ b) != 0 )
Console.Write( "Not Same" );
else
Console.Write( "Same" );
}
// Driver code
public static void Main()
{
// Calling Function
areSame(10, 20);
}
} // This code is contributed by Nitin Mittal. |
<script> // Finds if a and b are same. function areSame(a, b)
{ if (a^b)
document.write( "Not Same" );
else document.write( "Same" );
} // Driver code areSame(10, 20); // This code is contributed by Surbhi Tyagi. </script> |
Not Same
Time Complexity: O(1)
Auxiliary Space: O(1)
Method 2: We can subtract the numbers. The same numbers yield 0. If the answer is not 0, the numbers are not the same.
// CPP code to check if 2 numbers are same #include <bits/stdc++.h> using namespace std;
// Finds if a and b are same void areSame( int a, int b)
{ if (!(a - b))
cout << "Same" ;
else
cout << "Not Same" ;
} // Driver code int main()
{ areSame(10, 20);
return 0;
} |
// Java code to check if 2 numbers are same class GFG{
// Finds if a and b are same

else
System.out.println( "Not Same" );

areSame( 10 , 20 );

Method 3: The bitwise AND of one number and the complement of the other number is zero if they are the same, and non-zero if they are not the same.
Below is the implementation of the above approach:
#include <iostream> using namespace std;
// Finds if a and b are same. void areSame( int a, int b)
{ if (a & (~b))
cout << "Not Same" << endl;
else
cout << "Same" << endl;
} // Driver code int main()
{ areSame(10, 20);
} // This code is contributed by phasing17 |
import java.io.*;
class GFG {
// Finds if a and b are same.
static void areSame( int a, int b)
{ if ((a & (~b)) != 0 )
System.out.println( "Not Same" );
else
System.out.println( "Same" );
} // Driver code public static void main (String[] args) {
areSame( 10 , 20 );
}
} // This code is contributed by Pushpesh Raj. |
# Python code to check if 2 numbers are same # Finds if a and b are same def areSame(a, b):
if (a & ~b):
print ( "Not Same" )

class GFG
{ // Finds if a and b are same.
static void areSame( int a, int b)
{
if (Convert.ToBoolean(a & (~b)))
Console.WriteLine( "Not Same" );
else
Console.WriteLine( "Same" );
}
// Driver code
public static void Main( string [] args)
{
areSame(10, 20);
}
} // This code is contributed by phasing17 |
//JavaScript code to implement the approach // Finds if a and b are same. function areSame(a, b)
